INTERESTING! Hmmm, now we have to realize that the Bible has been re-writen so many times by (sorry guys) men of that time,how do we really know what that first sin was? Also,if Adam and Eve "were" the first humans,who wrote all this down? And this is the one that always threw me,who the heck wrote it all down in the first darn place..I was raised Christian and was always asking questions that bugged me,I got slapped in the mouth once for defending Mary Maggie..
Which I still defend her and Jesus and always will,but then thats another issue...I also have other ideas on where we came from in the first place,also another issue...So the first sin,it could be any number of things..It seems we humans have been guilty of so many first sin's lol, it seems we are never out of trouble for something or other..But,I love this topic,it makes you think of "why/when/how"........
