So where are the bolts? First of all, we can not say that all Native people have been DNA sequenced enough to see if all their ancestors go back to one person in Africa, no "race" of people have for that matter. Second, why is the BBC such a credible source, after all, the Brits are the ones, without the help of Comet Dumb Dumb, destroyed the civilizations of the Natives not so long ago. Third, there is mounting evidence that there were most likely several migrations from several parts of the world, from several ports of entry (even the BBC got in on this one, regarding the 38,000 year old footprints found in Mexico. Forth, the Clovis People probably migrated if such a disaster had happened to other regions of the globe.
The real problem is in believing other theories other than what we were taught in grammer school, about the Bering Strait migration and the last ice age, etc. We've since had to redo this stupid theory several times, you'd think these pendejos would just stop talking until the final proof comes forth, but nooo, because someone in a monkey suit needs fund money for their experiments and studies. Everyone wants to feel important with their new theories. Oh well, what about this one: perhaps, there was an impact, but not as fatal, some animals died off, some humans died off. Heck, according to the academia, they were only living to forty anyway, so it must have been pretty easy for that to happen. Life went on, pretty much undisturbed, until the English Only crowd came in and dessimated the original populations down to what is now only 1 percent, destroying over two thousand Native languages along with them. The same thing happened down south with the Spanish Only hoodlums. Then they all set about to reteach everyone with their theories, replacing nearly all Native thought with Euro-centic thought through various forms of intimidations and cruelties, until the internet came along so a bunch of Nerds could sit and ponder these things, poiting out tid bits of this New knowledge to each other, further trying to destroy any last fragment trace of anything Native, whether in thought or word. Then Yellowstone started to rumble, causing many to realize, "hey, maybe we don't know as much as we thought?" Hey, maybe Nature will once more bring US all to the brink of destruction? Maybe, some will be left to tell all about US, and what not to do the next time around, thus setting off a chain of events that will herald in a 'new' Platinum Age of Humanity, where we aren't so busy digging in the dirt looking for clues to who we are TODAY? Hm? Maybe not. Oh, well, just a fantasy.
