The Earth is round because many explorers have proved they can sail around the world, and it's also what I've believed my whole life. If the Earth wasn't round, how could people travel across the Pacific ocean without falling into outer space? It would also look weird from outer space looking down at a flat planet. 

The earth is round because duh. And what Fleet and TheaterGirl said. Also, when you look at the horizon, it’s curved. And the reason we can’t see stuff past the horizon is because the earth is round. If you stand by the ocean or a big lake, you can watch a sailboat sail off into the horizon, and you’ll still be able to see the sail peeking up after the boat has disappeared, because of the curve of the earth. I don’t think there’s really any evidence of the earth being flat. 

The earth is round. There is physically no way for it to be flat - gravity would pull it back into a sphere anyway. For the earth to be flat, gravity would have to pull straight down, not to the center of mass. If this was true, the earth wouldn't be able to orbit the sun and the moon wouldn't be able to orbit the earth. It just doesn't work.

But, since no one is arguing for the other side, I suppose I'll bring up some points for that.

The earth is flat because it appears to be flat. If I look into the distance, everything appears to be flat. The earth doesn't curve. If the earth did curve, we would be able to see that. Therefore, the earth is flat.

(and then refuting those points because why not)

The earth is so large that we cannot see the curving of the earth. However, when astronauts went into space, they were able to see that the earth is curved. And no, it's not possible that the moon landing was faked. Too much effort went into doing that; there's footage of the rocket taking off; people died for that to happen - don't you think if it was faked, they would have kept everyone alive? 

I can't help but feel a bit hopeless looking at this new generation, of which the debate of whether the earth is flat is an actual controversial matter. People from ancient Greece, for goodness sake, calculated the exact curviture of the earth. That was over two thousand years ago, and for these past two millennia people have demonstrated time and again that the earth is roughly spherical, whether it be an Egytian scholar from the ancient times, or Ferdinand Magellan cirucumnavigating the earth, or NASA taking pictures from space. I'm fairly certain this counts as irrefutable evidence.

Y’all,,,, the earth is a velociraptor. smh

Me speaking for my friend Pseudonymous Icongito Spy, it's flat because theoretically if it was round you could walk right off it. Ugh, I hate that perspective. It makes sense but IT'S NOT TRUE!!!!!!!!! *pseudonymous slaps cookie* ouch, okay!
