The earth is not flat

Seriously i can't stand these people, we are in 2019 and still people believe that the earth is flat. People who believe in the flat earth use the argument that the horizon is flat, but if the earth was flat, then there would be no horizon.

Also if it would be flat i should see mount everest and Burj Khalifa from here. And i should see all the stars. And the sun at night. The moon is sometimes out at night and sometimes not which would be inconsistent on the flat earth, And then all planets in the solar system would be globes but earth would be a disc which would be crazy, or all the other planets would be discs that are facing us which would be also stupid.
