Let's have a serious debate about the earth being round. (Side note, I don't believe in the flat earth theory.) Humans have known for centuries now that the earth is round. Aristotle actually noticed the shadow on the moon was always round. And the only shape that always has a round shadow is a sphere. The earth has to be round. A man actually measured the circumference of the planet. How could the earth be round if at mid day of the solstice on the equator we don't have a shadow. But 500 miles away there is a shadow of 7.2 degrees. That would mean the earth is roughly 25,000 miles. What about the hundreds of astrolabs that claim to be able to send signals to the moon. There is a device on the moon from the last moon landing that we can contact. We can find it's location even during the day. Suppose the earth isn't a sphere. Where would the drop off be? The atlantic or the pacific ocean? Are the hundreds of sailors and pilots that go through these every day liars also? What about the engineers at nasa and the government officials? That is a lot of people to be sworn to secrecy for the earth to be flat.
