I saw a football field size black triangle rotating above me silently. It was next level tech for sure. A tr-3b I would come to find out. The technology more than likely was recovered (ancient vimana) or discovered by the nazis towards the end of WWII. There are stories of farmers being picked up in the early 1900's by fanciful air ships, that technology never went public. More than likely there is a breakaway civilization of aryans, already traveling the stars. I was once skeptical of unknown aircraft, until I saw one, and had to get to the bottom of it. This is what research into this topic looks like. And it's fairly certain an evolutionary cousin of man still lives in the deepest woods. The reason theres no remains ever found is because they are probably cannabilistic and eat their dead for honor, and to keep hidden. The earth is most definitely round, mostly egg shaped though. Our monkey brains can't perceive the curvature of spacetime so it looks flat. The real argument is how our perception of spacetime is flawed, and how mass curves spacetime in, and gravity is still argued fundamentally, but the flat earthers are too lost in the weeds. And lack the iq points to handle complex thought.
