Research spherical earth
https://www.youtube.com/results?search_query=spherical+earthAround 350 BC, the great Aristotle declared that the Earth was a sphere (based on observations he made about which constellations you could see in the sky as you travelled further and further away from the equator) and during the next hundred years or so, Aristarchus and Eratosthenes actually measured the size of the Earth!
Even thousands of years ago people were smart enough to deduce the earth was round.
NASA already faked it in 350BC with CGI. Aristotle was a nasa puppet, nothing more.
