Do flat-earthers think that only the earth is flat?

They think those things are also flat, like essentially flat discs.

They don’t THINK – -someone told them that the Earth is FLAT !!

Probably not. Telescopes are too hard for them to use.

I wonder if FE proponents even believe that there’s a 3rd dimension.

There are people who believe space is just a lie made up by nasa, they claim that images of planets and space are digitally altered or fabricated. Other people believe that the sun, moon, and stars are not distant objects but rather lights or projections that move in a dome-like structure above the flat Earth. Stupid people believe a lot of stupid shit.

@cheebdragon, that would go beyond stupid. It’s called mentally ill at that point.
