I think back in 8 AD they still thought the world was flat!
Not everyone did. Aristotle put forth why he thought the world was round, but a couple centuries later around 200 BC Eratosthenes proved it was and determined its size no less.
I first learned that from Carl Sagan on Cosmos, but it is summed up here.users.zoominternet.net...

The Ancient Peruvians were more concerned with the dark areas of the Milky Way than actual stars and had a method of projecting/reflecting these regions upon their landscape. Say for example they picked out one area that to them looked liked a Lama - They reflected this in their clothing designs - In Native American clothing the patterns actually represent something of their beliefs. Geometry was known by ancient peoples - to create the Nazca lines is a simple use of geometry. A grid reference if you like

Uh, traveling into orbit isn't required to prove the Earth is round.

You can't prove anything without ultimately observing it. Theory only goes so far, even if it is extremely accurate. You can't tell for sure until you look.

I think you should learn about Eratosthenes.

Since you haven't been in orbit, do you believe the Earth is flat?
You should learn about Eratosthenes.
His calculations and methods proved that the Earth is round. There is no other explanation for his work.
