This is with all easily disproven conspiracy theories. Yes, there are many stupid people that believe these things because they saw a video and it was a simple explanation that appealed to them or because someone they like said it once, but some of the flat earthers are smart.

People often, for example, find religion after the death of a loved one. People also want to believe what others in their community believe, so belief can take hold easily once seeded into a community. We all like to think we are rational, we are not.
