>>15518687I had a conversation before today about solving the time travel paradox, time traveling would actually just create a new timeline, a so called sandbox timeline if one chooses to travel back in time on the very same timeline we are on now. This newly created timeline is branching of the time string we were on, it's an entirely new universe at this point with unwritten future.
This transition can happen because we can assume the axiom that our universe is part of a multiverse which contains infinite universes of possibilities. Therefore there are infinite identical copies of our universe and infinite universes which were following our timeline on Earth up to a specific point and branched off or are lagging behind in time and vise-versa.
tl;dr aliens don't have a need to time travel since it's the same as dimensional traveling, but with more disadvantages and no space for varieties, since you would still move in a realm things we are able to imagine with the laws of our universe. They do not need your sperm. The only aliens which will ever dig up a human on our planet in a million years are our evolved successors in the far future returning back home.
