One reason for scientific minds believing in a human God is that science does not disprove one. Actually, from a physics point of view, the idea of a God is actually highly supported.... there was nothing and then their was something and we cannot know before that because our universe did not exist before that. I worked with a group doing an engineering project for nasa and most of the group were INTJ, I was the only INFJ (and yes, I did an in depth sociological study on the group with their permission). What I found was that most of us are religious, only 1 of the 9 was not. Although, no one would/wanted to talk about religion when I tried to bring it up. They were actually rude about it when I tried to start a discussion as a group and not just with individuals. I was highly upset about it as they normally do not behave rudely and there was no cause for it when the discussion did not get into personal beliefs at all; I was most careful.
Another way, the way I look at religion is: it is a belief system, whatever belief system you happen to have, about the unknown. We will never know everything (Heisenberg's uncertainty principle) and how we choose to think about it is our belief system. This means that scientific thought is a belief system, but that does not make it contrary to a human God. Just because we don't know exactly how one could come about does not mean that it didn't... as we are not all powerful in our knowledge. A miracle does not stop being a miracle just because you know how it works. Probability determines what is likely, but so many things contrary to probability happen... at least around me and from what I have seen in my life.
If you want to know more, from a physics view point, about how physics and a human God can correspond then let me know and I would be happy to explain. Everyone has their opinions and those with strong thinking abilities are no different, we just analyze God in a different manner. I know that I dislike much of the sheep-like Christian behavior, those that are part of the "Christian ghetto" (have friendships with only other Christians) because those are the ones who seem so willing to believe without concrete reasoning or having thought about it. Those types, of any belief system, I have a hard time understanding. Question everything. After that, much really is opinion. Science can only give you so much, and much of that is only "likely" not definite... like predicting the future or the weather ;-p
