Just for argument's sake -
... If evolutionary theory is true, there were no physical Adam and Eve...
that doesn't follow. If there were an Adam and Eve, there's no reason for evolution to be invalid. It's always seemed obvious to me:
* Suppose there was an Adam and Eve.
* Suppose that evolution is a real thing.
There ya go. All done.
All the arguing about evolution vs. creationism is not a real argument. Once you get past the notion of existence, either the universe happened at some point a long time ago by accident, or on purpose, or more recently on purpose. That's the real argument. You're never going to prove it one way or the other - 'because god.'
But whether it was on purpose or by accident and how long ago isn't real important. What's important (if you lean that way) is science.
What happens happens "because science." Done.
And if you're religious, then science happens "because god[*]."
Move along. Nothing to see, here.
