Look - I know the Earth is a sphere because I’ve seen it myself from outer space.
It was during my third abduction.
Just after the physical exam and right before the sex encounter with the Nordic Alien female, one of the Grays (they act as workers for the Nordics and also as soldiers against the Reptilians from Draco) let me look out of the viewport.
They have big viewscreens like the ones on Star Trek that can magnify and enhance, but there are also several plain viewports on each of their ships. There is no refractive glass or anything in the port. It’s just an open spot in the hull that is sealed by a force field.
It’s a little disconcerting at first, as your natural instinct is to draw away from the open port. But once you get used to it the view is great.
And from there I saw with my own eyes the spherical Earth.
So there.
