Re: Interesting use of statistics... "lies, damned lies and statistics"
I would suggest a little better approximation of the time frame as 12900- 11600 yrs ago. Whatever happened around 12900-12800 years ago depending on age dating marked then end of the North American megafauna as well as most of the humans of the time and brought on a period called the younger dryas Cooling. I highly recommend Graham Hancocks' 'Magicians of the Gods' chapters 3&4 as an eye opener on this subject. His and Randall Carlsons' Theory involves a or a series of comet fragment impacts that relate directly to the meteor steam discussed above.
