"The two are separate for a reason. They address separate human needs"
Who says so, your? Why are you the authority that says the two must be separate?
"Why are you the authority that says the two must be separate?"
I was wondering the same thing. I find often the people who say the two must be separate are atheists.
Because they obviously are separate. They don't agree and the science is verifiable, the Bible is not. The faith is not subject to reason. Why is this so hard to explain?
