I think we're coming up on a major split in the timeline.
The sheeple who want to eradicate all germs and wash constantly in disinfectant, their descendants will be the grey's, that's why so many of em are seen in recent times and been abducting people and cows etc, they're coming back in time to see how they fucked up.
The rest of us, who don't wear the mask, will re-elect Trump and go to a glorious future of free energy and intergalactic colonization of the galaxies, our descendants are the Nordics. curiously, they are also our forefathers.
Or something like that.
