Well...by co-exist, I mean that you can't pretend to be both a scientist, and religious. It is a foregone conclusion that, sooner or later, the two will contradict one another. Then you're going to have to choose which one you are - a scientist, or a theist.
I really have to disagree with you on that one. Someone I know well is a staunch Southern Baptist, a believer in Jesus Christ as his savior, and has a PhD in physics. He has had no difficulty being both a scientist and a theist.
And how does he explain,
with physics, and science...oh, I dunno...alchemy (turning water to wine), or walking on water, or feeding thousands with five fish, or, here's a big one...
getting up after being dead for three days. How does your friend explain a zombie with physics, and science.
See. Either he just "shuts off" his rational brain, and ignores all of those things that science dictates simply can. not. happen, or he is lying to himself when he says he 'believes".
