Gas people.
Also, did you ever consider that since the light that has hit us and reflected off is forever projecting out into space, actually every human and event that’s ever existed outdoors to an open sky during the daytime will forever be theoretically visible and realistically catapulting through space forever and ever until it bumps into something or dissipates in space dust?
And, further to that, that if anyone was looking from afar, they’d only see the tops of our heads? And during the daylight only? No clouds, no night and no indoors??
Could it be that there are actually gas people living on like Neptune or Jupiter, but they’re living in consistently overcast skies?
