Here’s a huge post for you [MENTION=9401]LucyJr[/MENTION]
Just thought I would give you some of the scientific knowledge that is out there. Like I said...I am not out to disproved anyone’s religion...I am really trying to show that they can go hand in hand with evolution once you take a step back and accept that we were created that way...that what is in the bible is a parable meant to explain things to the people back then...who for sure wouldn’t understand the evolutionary process, or the process by which God used it to create us.
Here is the proof that is out there -
"Amino acid racemization dating is a technique that is used to date fossilized objects up to several million years in age. The naturally occurring amino acid
molecules usually possess a
carbon centre with four different groups joining it; a
hydrogen atom, the amino group, the acid group (hence the name of the class of molecule) and a side chain, which is what distinguishes amino acids. In three dimensional space, such a molecular topology can occupy one of two configurations. Convention labels these as D or L, which are referred to as stereoisomers and are essentially mirror images of each other. The ratio of these two isomers is initially unequal. With only one exception, naturally occurring amino acids used in polypeptide synthesis are in the L form. Over time this will decay to a more balanced state in a process called
racemization, where the ratio between L and D stereoisomers will be equal (a racemic mixture).
Measuring the degree of racemization and other known quantities can show an estimated age of the sample. This is measured fairly unambiguously by the fact that different stereoisomers rotate plane polarised light in opposite directions (it is this interaction that determines the D and L labels) and so a ratio can be determined by contrasting an unknown sample with a pure D or L sample and a racemic mixture. By measuring the racemization of the amino acid isoleucine, for example, objects can be dated up to
several million years old.[SUP]
[2][/SUP]
While it is true that there can be great variability on the rate at which amino acids undergo racemization, the changes in humidity, temperature, and acidity required to make the oldest known samples conform to a young earth (under 6000 years) view are completely unreasonable. Such conditions would destroy all traces of the amino acids rather than just leave a racemic mixture of the molecules behind.
[edit]Baptistina asteroid family
The Baptistina asteroid family is a cluster of asteroids with similar orbits. This group was produced by a collision of an asteroid 60 kilometers in diameter with an asteroid 170 kilometers in diameter. Researchers from the Southwest Research Institute (SwRI) and the University of Prague have traced the orbits of these asteroids back from their current locations and estimated that the original collision happened 160 (±20) million years ago.[SUP]
[3][/SUP] 2011 data from the Wide-field Infrared Survey Explorer has revised the collision date to
80 million years ago.[SUP]

[edit]Continental drift
Fossil areas across landmasses.
Based on the continuity of fossil deposits and other geological formations between the South American and African tectonic plates, there is much evidence that at some point in history the two continents were part of the same landmass. Because tectonic drift is an incredibly slow process, the separation of the two landmasses would have taken millions of years. With modern technology, this can be accurately quantified. Satellite data has shown that the two continents are moving at a rate of roughly 2 cm per year (roughly the speed of fingernail growth), which means that for these diverging continents to have been together at some point in history, as all the evidence shows, the drift must have been going on for at least
200 million years.[SUP]
[5][/SUP]
[edit]Coral
Corals are marine organisms that slowly deposit and grow upon the residues of their calcareous remains. These corals and residues gradually become structures known as coral reefs. This process of growth and deposition is extremely slow, and some of the larger reefs have been "growing" for hundreds of thousands of years. The Great Barrier Reef Marine Park Authority estimates that corals have been growing on the Great Barrier Reef for
25 million years, and that coral reef structures have existed on the Great Barrier Reef for at least
600,000 years.[SUP]
[6][/SUP]
[edit]Cosmogenic nuclide dating
The influx of cosmic rays onto the earth continually produces a stream of cosmogenic nuclides in the atmosphere that will fall to the ground. By measuring the build-up of these nuclides on terrestrial surfaces, the length of time for which the surface has been exposed can be inferred. This technique can be used to date objects
over millions of years old.[SUP]
[7][/SUP]
[edit]Dendrochronology
Clearly defined tree rings.
Dendrochronology is a method of scientific dating which is based on annual tree growth patterns called tree rings. The rings are the result of changes in the tree's growth speed over the year (since trees grow faster in the summer and slower in the winter). The age of a tree can be found by counting the rings and is the only method on this list that can date events
precisely to a single year.
Now, any date derived from one individual tree is not in itself contradictory to the recent creation doctrine, since even the longest lived types of tree do not live longer than 5,000 years or so. However, it is possible to extend the chronology back over many different trees. This is done by taking the matching up living tree rings with dead tree rings, which go on longer than the living rings. Because the thickness of tree rings varies with the climate, a sequence of
thick ring, thin ring, thin ring, thick ring, thick ring, thick ring, thin ring, thick ring is strong evidence that the corresponding rings formed at the same time. By observing and analyzing the rings of many different trees from the same area, including fossil trees, the tree ring chronology has been pushed back in some areas as far as
11,000 years.[SUP]

[edit]Distant starlight
The Hubble Deep Field, taken in 1996, showing light that has been in the cosmic vacuum of space for billions of years, not thousands.
See the main article on this topic: Starlight problem
The fact that distant starlight can be seen from Earth has always been a major problem for the young Earth idea. Because the speed of light is finite, what you are actually seeing when you look at an object is an image of that object
from the past. "From the past" here has a few caveats regarding the
relativity of our concept of the past, the future, and now. In the BBC
Horizon program
What Time Is It? physicist and former pop-synth player
Brian Cox suggested that, as information cannot travel faster than light, and that time and space are relative, it can be considered that that the stars actually
are what they look like "now", in a manner of speaking. Either way, though, the bottom line is still the same; the light has travelled a certain distance, for a certain time, before arriving on Earth to be seen by our eyes or telescopes. We can use this data to put a minimum time on the existence of the universe, by looking at how long some light has been travelling for.
On Earth, the delay caused by the speed of light is incredibly minor — when you look at an object a mile away, the light has been travelling for five microseconds. When you look at the Sun, you are seeing light that has been in transit for 8.3 minutes. It's more noticeable with sound and distant objects, but only because the light from things such as distant explosions or jet fighters is so much faster. There's still a delay and transit time for the information that says whatever made the light/sound must have been around that long ago to produce it.
On the cosmic scale of things, this delay is far from minor and really is noticeable. When astronomers look at the closest star to Earth (Alpha Centauri), which is roughly four light years away, they are seeing the star as it was four years ago from our perspective. When astronomers look at objects in the region of space known as the "Hubble ultra deep field", they are seeing the stars there as they were over
ten billion years ago. Light we are receiving from these fields has been travelling for ten billion years, and the universe must have, therefore, existed long enough for that transit time to take place.
Therein lies the problem for young Earth creationism; if the universe is only 6,000 years old, how can objects billions of light years away — and therefore billions of years old — be seen?
There are a few creationist "zingers" to solve this problem, but are almost exclusively centred around
pretending the problem doesn't exist. One is omphalism, which suggests the light was already in place and on its way 6,000 years ago, which is basically like saying that "6,000 years ago, the world was created 14 billion years ago", which is a form of
Last Thursdayism. They also like time dilation fields and
changing the speed of light, but as this requires a lot of
Goddidit to make it work, as there is zero evidence for why the speed of light should change. There are a lot of issues surrounding changing fundamental physical constants such as
c, namely that according to E=mc[SUP]2[/SUP], increasing
c to make the world 6,000 years old would lead to normal radioactive decay blowing the planet up.
Qualified astrophysicist
Jason Lisle came up with the "
anisotropic synchrony convention", which exploits how to reliably measure of the speed of light, but suffers from
special pleading in that it assumes a highly unlikely physical reality deriving from a mathematical quirk is
literally true - and there is
no additional evidence for such a thing.
[edit]Erosion
Many places on
Earth show evidence of erosion taking place over very long time periods. The
Grand Canyon, for instance, would have taken
millions of years to form using the normal rate of erosion seen in water.[SUP]
[9][/SUP] Nevertheless, Young Earthers insist it was cut in a few years following the Great Flood - but in order for this to happen the rocks of the Kaibab Plateau would have needed to have the solubility of granulated sugar, rather than the more solid stone that it's made of.[SUP]
[10][/SUP]
VenomFangX of YouTube claimed that the Grand Canyon would have formed in about "5 minutes", which at the very least would require the water to travel 5-6 times the speed of sound.[SUP]
[11][/SUP]
In the case of the Yakima River in Washington State between Ellensburg and Yakima, the river meanders with many oxbows typical of a slow-moving river on a plain, yet it is set within a deep canyon with visible layers of erosion. The only possible explanation is that the pre-existing river maintained its original bed as slow tectonic forces caused the surrounding land to rise underneath and around it.
[edit]Fission track dating
Fission track dating is a radiometric dating technique that can be used to determine the age of crystalline materials that contain
uranium. As uranium decays, it sends out atomic fragments, which leave scars or "fission tracks" in crystalline structures. Because decaying uranium emits fragments at a constant rate, the number of fission tracks correlates to the age of the object.[SUP]
[12][/SUP] This method is generally held to be accurate, as it shows a high degree of concordance with other methods such as potassium-argon dating.[SUP]
[13][/SUP]
[edit]Geomagnetic reversals
A geomagnetic reversal is a change in the polarity of the Earth's magnetic field. The frequency at which these reversals occur varies greatly, but they usually happen once every
50,000 to 800,000 years, and generally take thousands of years.[SUP]
[14][/SUP] This fact is obviously inconsistent with the notion of a young Earth; around 171 reversals are geologically documented, which would make the Earth at least 8.5 million years old.[SUP]
[5][/SUP]
[edit]Helioseismology
The composition of the Sun changes as it ages. The differing composition changes the way sound waves behave inside the Sun. Using helioseismic methods (models of pressure waves in the sun), the age of the Sun can be inferred. Using this method, an Italian team came up with an age of
4.57 +/- 0.11 billion years.[SUP]
[15][/SUP]
[edit]Human Y-chromosomal ancestry
See the main article on this topic: Y-chromosomal Adam
The Y-chromosome, unlike most
DNA, is inherited only from the father, which means that all DNA on the human Y chromosome comes from a single person. This does not mean that there was only one person alive at that time, but that a single man's Y-chromosomal DNA has out-competed the other strains and is now - not taking into account smaller and less drastic mutations - the only one left. Because the only factor affecting the makeup of the DNA on the chromosome is
mutation, measuring mutation rates and extrapolating them backwards can tell you when this man lived. The most recent calculations put this common ancestor as having lived
340,000 years ago.
[edit]Ice layering
A section of an ice core with clearly defined annual layers.
Ice layering is a phenomenon that is almost universally observed in ice sheets and glaciers where the average temperature does not rise above freezing.
Annual differences in temperature and irradiation cause ice to form differently from year to year, and this generates alternating layers of light and dark ice, much like tree rings. This method is considered a relatively accurate way to measure the age of an ice sheet, as only one layer will form per year. While there have been a few cases where several layers have formed per year, these incidents do not challenge the ability of ice layering to provide a minimum age, as these false layers can be discerned from the real thing upon close inspection.
Currently, the greatest number of layers found in a single ice sheet is over 700,000, which clearly contradicts the idea of an Earth less than 10,000 years old. Even if one were to assume an absurdly high average of ten layers per year, the age demonstrated by this method would still be far greater than that suggested by young Earth creationists.[SUP]
[16][/SUP]
Nevertheless, the
minimum age of the Earth identified by these means is
160,000 years. (+/- 15,000 years.)
[edit]Impact craters
The number of impact craters can provide a probable lower limit on the age of the
Earth. Asteroid strikes that can produce craters on the order of kilometers across are extremely infrequent occurrences; the chance of an asteroid with an Earth-crossing orbit actually striking the
planet has been estimated at
2.5 x 10[SUP]−9[/SUP] yr[SUP]−1[/SUP], and when multiplied by the estimated number of Earth-crossing asteroids this approximates about one collision for every 313,000 years.[SUP]
[17][/SUP] If this frequency is correct, the number of impact craters on Earth were it only a few thousand years old should be very few. The most logical number of observable >1km impact craters for a young Earth would in fact be something like
zero — a number that is completely at odds with the observable evidence, since over one hundred such craters have been discovered .[SUP]
[18][/SUP]
A crater 1,200 meters in diameter.
Even if creationists were to present some scenario in which many dozens of large asteroids could hit the Earth in less than 6000 years, there are still tremendous problems with this idea. The largest asteroid impacts are some of the most catastrophic events the world has ever seen. In
Antarctica there is a crater 500 km in diameter which is calculated to have been caused by an asteroid 48 km in diameter roughly 250 million years ago.[SUP]
[19][/SUP] How the life we see today could have survived such an incident (if it had occurred in the last 6000 years) is a serious problem for YECs; an asteroid impact that big would have led to the extinction of all medium to large size species, an event that — given the creationist model; short time frame, no evolution — the world would have never recovered from.
[edit]Iron-manganese nodule growth
An iron-manganese nodule
Beryllium-10 ([SUP]10[/SUP]Be) produced by cosmic rays shows that iron-manganese nodule growth is one of the slowest geological phenomena. It takes
several million years to form one centimeter (and some are the size of potatoes).[SUP]
[20][/SUP] Cosmic ray produced [SUP]10[/SUP]Be is produced by the interactions of protons and neutrons with nitrogen and oxygen. It then reaches the earth via snow or rain. Since it is reactive, it gets absorbed by detritus material, within a timespan of about 300 years- very short compared to its half-life. Thusly, [SUP]10[/SUP]Be is excellent for use in dating marine sediment.
[edit]Lack of DNA in fossils
Deoxyribonucleic acid (DNA), the universal carrier of genetic
information, is present in all organisms while they are alive. When they die, their DNA begins to decay under the influence of hydrolysis and oxidation. The speed of this decay varies on a number of factors. Sometimes, the DNA will be gone within one century, and in other conditions, it will persist for as many as one million years. The average amount of time detectable DNA will persist though is somewhere in the middle; given physiological salt concentrations, neutral pH, and a temperature of 15 °C, it would take around
100,000 years for all the DNA in a sample to decay to undetectable levels.[SUP]
[21][/SUP]
If fossils of the
dinosaurs were less than 6,000 years old, detectable fragments of DNA should be present in a sizable percent of dinosaur fossils, especially in the Arctic and Antarctic regions where the decay of DNA can be slowed down 10-25 fold. A claim that soft tissues in a
Tyrannosaurus fossil had been recovered in 2005[SUP]
[22][/SUP] have since been shown to be mistaken,[SUP]
[23][/SUP] supporting the idea that dinosaur fossils are extremely old.[SUP]
[24][/SUP]
[edit]Length of the prehistoric day
Work by John W. Wells of Cornell University, New York has shown that certain pieces of extremely old coral show evidence of a growth rate which reflects a time when a year had 400 days of 22 hours each.[SUP]
[25][/SUP] Because the rate of change of the rotation of the Earth is relatively predictable—about 0.005 seconds per year—one can calculate the last time a year had 400 days, which was about
370 million years ago (which is also about the same as radiometric dating of the coral).[SUP]
[26][/SUP]
[edit]Lunar retreat
South African rocks studied by geologist Ken Eriksson contain ancient tidal deposits indicating that at some point in the past, the
Moon orbited "25-percent closer to Earth than it does today."[SUP]
[27][/SUP] The distance between the Earth and the Moon is 384,403 kilometers, so for Ken Eriksson's work to fit with a YEC timescale the Earth would have to have been receding at a speed greater than 15 kilometers per year. However, the Moon is currently receding from the Earth at a rate of 3.8 centimeters per year.[SUP]
[28][/SUP]
[edit]Naica megacrystals
The Naica Mine of Chihuahua, Mexico is the home of some of the largest gypsum
crystals on earth. Specimens in the area have been found to exceed 11 meters in length and 1 meter in width. Based on classical crystal growth theory, these crystals are older than
one million years.[SUP]
[29][/SUP]
[edit]Nitrogen impurities in natural diamonds
Nitrogen is the most common impurity in natural diamonds, sometimes by as much as 1% by mass. Recently formed diamonds, however, have very little nitrogen content. A major way synthetic diamonds are distinguished from natural ones is on the basis of nitrogen permeation. It takes long periods and high pressures for the nitrogen atoms to be squeezed into the diamond lattice. Research on the kinetics of the nitrogen aggregation at the University of Reading have suggested that a certain type of diamond, I[SUB]a[/SUB] diamonds, spend
200-2000 million years in the upper mantle.[SUP]
[30][/SUP]
[edit]Oxidizable carbon ratio dating
Oxidizable carbon ratio dating is a method for determining the absolute age of charcoal samples with relative accuracy. This dating method works by measuring the ratio of oxidizable carbon to organic carbon. When the sample is freshly burned, there will be no oxidizable carbon because it has been removed by the combustion process. Over time this will change and the amount of organic carbon will decrease to be replaced by oxidizable carbon at a linear rate. By measuring the ratio of these two allotropes, one can determine ages of over
20,000 years ago with a standard error under 3%.[SUP]
[31][/SUP]
[edit]Permafrost
The formation of permafrost (frozen ground) is a slow process. To be consistent with the young earth creationist model, which states that all sediment was deposited by the
global flood, there would have to be absolutely no permafrost present at the end of the flood, because any permafrost that was present at the moment of creation would have been melted during the flood.
Because earth is a good insulator and permafrost forms downward from the surface, it would have taken much more than the few thousand years allotted by creation theory to produce some of the deepest permafrost. In the Prudhoe Bay oil fields of
Alaska, the permafrost which extends over 600 meters into the ground is believed to have taken over
225,000 years to reach present depth.[SUP]
[32][/SUP]
[edit]Petrified wood
See the main article on this topic: petrified forest
The process in which wood is preserved by permineralization, commonly known as petrification, takes extensive amounts of time. Gerald E. Teachout from the South Dakota Department of Game has written that "the mineral replacement process is very slow, probably taking
millions of years".[SUP]
[33][/SUP]
It is true that in the laboratory petrification can be achieved in a matter of months, but petrification is far slower in natural conditions.
[edit]Radioactive decay
Radioactive decay is the constant predictable decay of unstable atoms into more stable isotopes or elements. Measurements of atomic decay are generally considered one of the most accurate ways of measuring the age of an object, and these measurements form the basis for the scientifically accepted age of the Earth. There are many different variations of the radiometric dating technique such as radiocarbon, argon-argon, iodine-xenon, lanthanum-barium, lead-lead, lutetium-hafnium, neon-neon, potassium-argon, rhenium-osmium, rubidium-strontium, samarium-neodymium, uranium-lead, uranium-lead-helium, uranium-thorium, and uranium-uranium, of which every single one will date objects
far older than 10,000 years.[SUP]
[34][/SUP]
Because radiometric dating is one of the most commonly used methods of determining age, these techniques are under constant attack from young earth supporters. A few creationists, armed with only a cursory knowledge and a desire to think that they're better than scientific "experts", may misunderstand radiometric dating and just
not believe it works. This is often accompanied by ignoring the high concordance of radiometric methods.
However, the most frequently used method of attack is to give examples of objects of known ages that were dated incorrectly. These instances are by far the exception rather than the rule and are usually due to unforeseen contamination or other errors that can be quickly identified and compensated for. This is not "cheating" and forcing results to confirm to expectations as many young earth creationists may claim, it is making the data as accurate and precise as possible (if it is "cheating" then cleaning your camera lens to get a better and clearer picture is also cheating).
[edit]Relativistic jets
A drawing of
quasar GB1508 and its relativistic jet
A relativistic jet is a jet of plasma that is ejected from some quasars and galaxy centers that have powerful magnetic fields. It is conjectured that the jets are driven by the twisting of magnetic fields in an accretion disk (the plate-like cloud of matter) found encircling many celestial objects. In super-massive bodies, immensely strong magnetic fields force plasma from the accretion disk into a jet that shoots away perpendicular to the face of the disk. In some cases, these columns of plasma have been found to extend far enough to refute the idea of a young universe.
For example, the quasar
PKS 1127-145 has a relativistic jet exceeding one million light years in length.[SUP]
[35][/SUP] Because the
speed of light cannot be exceeded, this column must be over
one million years old. Moreover, these jets are generally billions of light years from Earth, meaning they were at least a million years old
several billion years ago due, again, to the speed of light.
[edit]Rock varnish
Rock varnish is a coating that will form on exposed surface rocks. The varnish is formed as airborne dust accumulates on rock surfaces. This process is extremely slow; between 4 μm and 40 μm of material forms on the rock every thousand years, and instances of 40 μm of accumulation are very rare.[SUP]
[36][/SUP] Because the rate of accumulation is generally constant, measuring the depth of the varnish can provide dates for objects up to
250,000 years old.[SUP]
[37][/SUP]
[edit]Seabed plankton layering
Fossils of dead plankton that layer on the ocean floor is used to gauge temperatures from the past, based on the chemical changes of Crenarchaeota, a primitive phylum of microbe. Much like ice layering and dendrochronology, researchers drill through the ocean floor to extract samples which indicate annual temperature fluctuations in the plankton fossils, or "chemical rings" as it were. A 2004 pioneering expedition to the
Arctic Ocean near the North Pole collected samples dating back to over
56 million years of temperature dating.[SUP]
[38][/SUP]
[edit]Sedimentary varves
Varves are laminated layers of sedimentary rock that are most commonly laid down in glacial lakes. In the summer, light colored coarse sediment is laid down, while in the winter, as the water freezes and calms, fine dark silt is laid down. This cycle produces alternating bands of dark and light which are clearly discernible and represent, as a pair, one full year. As is consistent with the old earth view, many millions of varves have been found in some places. The Green River formation in eastern Utah is home to an estimated
twenty million years worth of sedimentary layers.
The creationist response is that, instead of once per year, these varves formed many hundreds of times per year. There is, however, much evidence against accelerated formation of varves.
- Pollen in varves is much more concentrated in the upper part of the dark layer, which is thought to represent spring. This is what would be expected if varves formed only once per year because pollen is much more common at this time.[SUP][39][/SUP]
- In Lake Suigetsu, Japan, there is a seasonal die-off of diatoms (calcareous algae) that will form layers in the bottom of the lake along with the sedimentary varves. If the 29 thousand varves in the lake formed more than once per year, there should be several sediment layers for every layer of deceased algae. However, for every one white layer of algae in Lake Suigetsu, there is only one varve.[SUP][40][/SUP]
- The varve thickness in the Green River formation correlates with both the 11 year sunspot cycle and the 21 thousand year orbital cycle of the earth.[SUP][41][/SUP]
[edit]Space weathering
Space weathering is an effect that is observed on most asteroids. Extraterrestrial objects tend to develop a red tint as they age due to the effects of cosmic radiation and micrometeor impacts on their surfaces. Because this process proceeds at a constant rate, observing the color of an object can provide the basis for a generally reliable estimate. The ages provided by this dating technique
exceed millions of years.[SUP]
[42][/SUP]
[edit]Stalactites
A stalactite
A stalactite is a mineral deposit that is usually - though not exclusively - found in limestone caves. They are formed on the ceilings of caverns by the slow deposition of calcium carbonate and other minerals as they drip, in solution, over the stalactite. These formations take extremely lengthy periods to form; the average growth rate is not much more than 0.1 mm per year (10 centimetres (4 inches!) per thousand years). With such a slow rate of formation, if the earth was less than ten thousand years old we would expect to see the largest stalactites being not much longer than one metre.[SUP]
[26][/SUP] In fact stalactites frequently reach from the ceiling to the floor of large caverns.
It is true that cases of accelerated growth have been observed in some stalactites, but rapid growths are only temporary, as the rapidly growing stalactites quickly deplete the surrounding limestone.[SUP]
[26][/SUP]
[edit]Thermoluminescence dating
Thermoluminescence dating is a method for determining the age of objects containing crystalline minerals, such as ceramics or lava. These materials contain electrons that have been released from their atoms by ambient radiation, but have become trapped by imperfections in the mineral's structure. When one of these minerals is heated, the trapped electrons are discharged and produce light, and that light can be measured and compared with the level of surrounding radiation to establish the amount of time that has passed since the material was last heated (and its trapped electrons were last released).
Although this technique can date objects up to approximately
230,000 years ago, is only accurate on objects 300 to 10,000 years in age. This is, however, still over 4,000 years older than the creationist figure for the age of the earth.[SUP]
[43][/SUP][SUP]
[44][/SUP]
[edit]Weathering rinds
Weathering rinds are layers of weathered material that develop on glacial rocks. The weathering is caused by the oxidation of magnesium and iron rich minerals, and the thickness of this layer correlates with the age of a sample. Certain weathering rinds on basalt and andesite rocks in the eastern
United States are believed to have taken over
300,000 years to form.[SUP]
