If the Earth was flat, the Moon should be off the far side of the Earth, which means that if you can see the Moon, you should also be able to see all the buildings, mountains etc as well because they're between us and the Moon.
But in reality (picrel) you don't see anything besides the Moon. This doesn't make sense in the context of the flat earth theory. The simplest solution being the best one, flat earth theory is most likely wrong.
