>>3908599(start of part 7) There's a book by Ellis Silver called 'Humans Are Not From Earth: A Scientific Evaluation Of The Evidence'. He says (among other things) that sunburn, our relatively high chance of experiencing back pain and pain during labour are types of evidence that Earth is not an optimal environment for human beings and that we come from elsewhere.
My theory regarding the origin of the human species is that the human species comes from elsewhere in the Milky Way galaxy and, at some point in the distant past, our extremely ancient ancestors colonised vast swathes of the Milky Way galaxy (and are possibly still doing so) and both Mars and Earth were colonised by them along the way. There are pyramidal structures and a Sphinx-like object in various NASA photos of Mars. I also think that a fiercely destructive interplanetary war caused the destruction of a planet that used to exist between Mars and Jupiter, leaving only the asteroid belt that we know today. This war also sterilised Mars, turning what was once a lush, verdant, Earth-like planet into a cold, lifeless desert. (end of part 7)
