Since Humans generally are considered to be Barbarians by the Galaxy for a variety of Reasons

 The Galaxy will tend to alter time lines in space or on planets so people from earth don't meet people (or beings) from other planets or Star systems. It is one way to prevent mass deaths and wars and whole species on various worlds being wiped out. Time alteration saves lives and planets.

For example, we have been saved from 50 or more nuclear blasts that took out everything from a City to a nation to the Earth itself since 1945 or 1950 already. this was done through the retroactive changing of time lines.

So, many of you are going to have memories of being nuked like I actually was in Nagasaki in 1945 as a child there. But, for me, the good thing about this was that I was karmically born in Seattle Washington as a white American. This was the U.S. karma for nuking my home city into dust. This is how karma actually works.
