I agree.<quoted text>
But Genesis, if it happened, regardless, of what timeline it followed, could not have occurred, because it doesn't match with what we today do know happened, and secondly, even if it had happened the way the stories tell, man would not have had that information at the time of the writing of those stories to have actually written them down.
If there was actually one physical first man (and woman), there would have been no form of any kind of recording the events, including word of mouth, because man would have developed language, and means of passing on what he later did with that language, many thousands or millions of years after the events. It is also believed by some that the mythical writings were written by the mythical Moses, who mythically, according to what believers state, lived only a few thousand years ago.
Which is why I've said countless times that Genesis isn't a literal account. It merely details what God did, not HOW He did it. Not WHEN He did it.
I don't think Adam was literally the first human man. I think he was more likely one if the first Homo sapiens on earth. I think that God watched evolution happen, according to His plan and when man was ready (evolved enough) God made Himself known.
