Absolutely. I think the problem is though there are many people who interpret 'Anything is theoretically possible' to mean 'Nothing is Proven and everything is EQUALLY as possible', which of course is not the same thing. Also just because there have been mistake in science such as the Ether doesn't mean every scientific principle is equally as likely to be incorrect. There could be some grand conspiracy and the Earth is Flat, but the probability is so low its a bit absurd to throw out Round Earth because we haven't all individually circumnavigated the globe. But its true, my version of blue may be different to some one elses, but often there is a shared concept that something is blue even if we view it in different ways. The boundaries from one thing to another may vary, but we can also say whatever we individually see, the light wavelength and spectrum is the same even if our brains interpret it differently. I don't fully write off the existance of a god or gods (however I do catagorically rule out any purely benevolent god due to experience. People I know have suffered. An all powerful being could stop suffering, so therefore if there is any god it does not conform to my idea of benevolence). But I have never experienced anything I cannot explain through scientific means or random chance. The only thing I can conclusively prove is my own existance. My eyes, ears and other senses can be fooled or lied to, but my individuality is a certainty. From that point I must assume anything I can personally experience is at least partially true, and any scientific model that represents what I see is also at least particially true. From that I trust in experts to understand their field and move it forward, and when there is enough support in a field to suggest a change in knowledge then I accept that. When multiple theories compete I choose the one that fits best with the knowledge I have. Also the idea that any religious text is 100% literal is bit problematic consider many suggest that the world is X thousand years old when the science suggests its Billions, but again as long as that view isn't held by a majority or enforced by those in power it doesn't hamper scientific progress.
