3/The Garden of Eden in JC isn't such a stretch if you also believe that the continents where all in one place and broke up after the flood.
That is a stretch about 100 million miles long and reaching to try and explain something that is way of. So, if this is to be true we would have to think that man has been around for millions of years, instead of the Christian held idea that it was 6,000 years. I don't remember God saying that the Ark story also mentioned continents moving and science would be able to find some evidence of something to extreme. Unless of course God is hiding it, easy answer used by most religion. I would say it is just "dumb dumb dumb"
