White people theory

Ok, there was a planet, little colder planet, between Earth and Mars, but, their population could never get along, so they end up in a massive thermonuclear war, blowing that planet off, making it in the asteroid belt, lot of those rocks and dust hit Mars and Earth, that is why we see rocks in only one side of Mars, it was little bit closer, but Earth got all that dust that blocking Sun, causing a little glaciation, that finished with dinosaurs, but not with local humanoids, they were smart enough to protect themselves, or a lot of them were living closer to the Ecuador, some how, they managed to live, they were darker skinned
Then, some how, may be because they have the technology, few of the inhabitants of the blown planet, made their way to Earth, they landed in Northern hemisphere, were today is Russia, off course, they were the elites of Blown planet, they were lighter skinned, but they were not many, so, a lot of their knowledge vanished, they created a book before the old testament, on toughs of their old planet
And now, those lighter skinned people may blow this planet as well
