Interesting topic though I don't think that Adam and Eve actually had a daughter they only had sons to best of my knowledge but my bible knowledge is rather limited (strange when you consider the fact that I am Catholic) but I don't really believe half the stuff the bible says especialy in regards to human evolution since there is so much evidence for the fact that we are related to apes. In fact our DNA is a 98% match to the DNA of the chimpanzee. However in regards to the story of The Garden of Eden Adam and Eve did commit the original sin of eating the forbidden frit and therefore were booted from there, but they actually didn't have any children until they had been booted out so even though I answered that Adam and Even and their son would be booted out for commiting the 'original sin' I personally don't think that would have been possible.
