So you really believe there was an apple a snake and two naked people? And they mated with whom? You are going to run into difficulties very quickly.

And yes mating with giants has to be physically impossible....giants femurs have been found over 5ft in length. A woman would be ripped apart.

And who told you that you accept the whole as accurate or nothing? Have you any idea of all the inconsistencies just in the four gospels alone? Have you any idea of the mistranslation s never mind interference by priests etc....or the fact that words have changed meanings in different languages.

You sound like a child believing in the fairy story they read
