-1 for steering this towards a religious debate.

I'm not religious and don't believe in a god, but who's to say there isn't a god? We still don't have an explanation for how we're here. Until then, I'd say it's as fair a theory as any. Folks who believe in a god simply have a reason to believe, and that works for them.

I'm almost with you on this one. I would equate it more to the concept of religion, then the concept of God. There are a number of ways to easily prove the Earth is not flat, but no real distinct way to prove a god does not exist.

The main difference is that the Flat-Earthers are a very small group, whereas those who believe in God is extremely large. The small group is seen as ridiculous, but since the larger group is popular belief, is not seen as absurd.

It is actually more absurd to me that a huge number of people still follow religions, than the fact that a super subset of people believe the Earth is flat.
