I'm struggling with this. Sure NASA lies, the moon landings were faked and there's dozens of fake space videos out there. Also we know for sure that governments and institutions would not hesitate to lie to us on a massive scale.
But seriously how could the earth possibly be flat? How else would you explain daylight cycles and time zones, which are so trivial to verify? How could they keep it secret when so many boat captains and aircraft pilots etc etc would have to be in on the lie? How is there not even one solid piece of evidence?
All conspiracy theories are true. Except this one.
