What is the freaking odds of the Nephilim who were taunting the people in the Middle East would all drown, be floating in the water, dead, for over a year and then wind up in a cave in, what is now known as Mexico? I would say that the odds would be as close to impossible as possible.
With Shoulders and arms bent forward, due to the many months of swimming and trying to crawl up the side of the ark.
And wind up in the sitting position at that!!
