How as an individual can I know if the Earth is a sphere or a flat disc? What experiment can I do that doesn't involve trusting information from a 3rd party that would prove what the geometry really is?

Go to a church, ask them what they believe. The truth is usually the opposite.
Lol,this is funny indeed.
It would be a lot funnier if it happened to have some truth in it.
This thread actually went to page 2 in the forum. Almost can't believe it.
