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.
So who were Adam and Eves' parents?
In any creation myth I know, Man1 and Woman1 were created by god[s]. The mechanism varies.
What does that have to do with whether or not evolution is a real thing, today? Don't argue creation, you can not win, and it really does not matter. You *can not* prove that god *does not* exist. Take a deep breath and repeat after me (from the first paragraph on Wikipedia - the second paragraph is crap that religious folks may or may not disagree with, but which *does not matter* - the rest of the article is good science):
Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.
That's it. Done. Basic science. There are plenty of young world issues - the answer to which is always "because that's how god made it." Freakin cope with it, already - either you believe that or you don't.
The question before us is:
Why does shit happen?
The answer is:
The question NOT before us is:
Why does science happen?
Because the answer to that could be
* Because god.
It's a fine argument to have, but it has shit-all to do with evolution.
