Why Human Ancestor left their Mother Planet and colonized the current Solar System and Earth?
The forgotten history of Human Ancestor on why they Colonized the Solar System and Earth was due to the Nuclear War they had in their Planet. Everything is made out of Atom not only in Earth but through out the Multiverse or Universes. Once Nuclear War is launched, the Planet will not be livable. It will alter everything in Nature including Animals and Human Beings. Because we have forgotten our true history, we will possibly repeat it again on Earth. This is a warning of the effect of Atomic Nuclear War.
