"The only theological difference between a creationist and and a theistic evolutionist, as far as I can see, is that the theistic evolutionist believes God used evolution as his tool to make Adam's body."
If Adam had sprung out of the earth via a process that unwinds over time, then the Eve part of the story has serious, serious problems, doesn't it? And rationally, doesn't it make the eve part fully deniable, regarding her origin? I'll answer your other questions after your response...
And rationally, doesn't it make the eve part fully deniable, regarding her origin?
Not necessarily. If the story is taken literally, it would only necessitate a one-shot miracle to create Eve. I don't see how any scientific evidence could rule it out.
That being said, I don't think the Eve story is meant to be taken literally. However, I don't see how it makes any theological difference whether it is literal or not.
BTW, aren't we getting off track here? I thought we were talking about whether evolution rules out sin.
