ELI5 How do flat earthers back up their belief?

I really don't understand how the people who believe the earth is flat justify their position.  What evidence do they show? I mean we have literally been to space and seen the Earth is a spheroid.

I can to a point understand why creationists don't accept evolution: some people just can't conceptualize the massive time involved in the evolutionary process, and stick to their fiction. But with the flat earthers,  we can actually see, in real time that the earth is not flat. Please, ELI5 what evidence they use to back up this belief!

Have you ever actually seen the Earth from that point of view? Evolution deniers are actually denying rock solid evidence observed first hand by scientists. Many people believe the scientists are being dishonest and therefore don't believe the claims, the same can be said with flat Earthers. They have never actually observed the Earth from any point where it looks anything other that flat, what, are they just supposed to take the scientists words for it?
