RE: Is the earth round or flat ? How do you know that its round ? who has proved it ?

“Flat Earthers” are honestly very stupid. Their logic doesn’t make sense whatsoever. There is OFFICIAL NASA PROOF that the Earth is round. Everyone knows this for a FACT. I’m tired of seeing people trying to claim that the Earth is flat. All of their “evidence” of the Earth being flat is totally ridiculous and has no sources. We’ve seen official pictures of space. Astronauts. The moon landing. It has been proven since Christopher Columbus sailed that the Earth is round. THERE IS A ROBOT ON MARS. You people are ridiculous and need to get your facts straight.
