gyroscopes that are free to move remain steady and don't. if it was a globe, it would rotate every 24 hours and show us the 'wobble' that is suppose to exist.

you can see lighthouses/mountains from miles away, so far in fact that they should be well below the horizon, yet we can still see them. impossible on a globe earth.

satellites are so prolific in the sky, per google, that you should see 500 satellites pass by the moon in 12 minutes.

we have independent balloons that have gone as high as twelve miles and never seen the curve.

nasa videos can be shown to be fake. combination of vomit comet and cgi.

the moon landings are provably false. read 'wagging the moon doogie' for a non-video proof, video proof is everywhere.
