Unless they just type "add more water" into the code and the simulation provides more water. Who tf really knows. We're all clueless about reality. Dome no dome. Flat, round, square who knows?

Nope.

Believe a video. Don't need video. Go outside look up. What do you see?

We going up there ourselves to see with our own eyes. Camera could be adding special flattening affects we aren't aware of. Do you want with?

You're moving the goalposts, there are countless amateur videos demonstrating there is no curvature

There are also countless amateur videos of rocket launches. And half hr later sightings by amateurs half way around the world. First sattelite in space put up by the Russians went round and round and amateurs could verify it with ham radios as it passed overhead. I'm OK with earth being flat but explain sattelites? Do you think they'r real? Or is that shit impossible and its all simulated
