It's simple really, if the earth is flat, then showing a picture of the edge should be simple. I do not spend very much time on here so I will bump this every now and then to see if someone has a pic. Should be pretty easy to get a pic of the edge if it's flat.

Also for all the mentally ill people out there that think the earth is flat, it is up to you to prove it. You show a pic of the edge of the earth and by god I will believe it. This world really needs help.
