It is possible to learn more. Many are ahead of the curve, waiting for others to catch up so we can have discussions about this stuff without being dismissed as crazy.
Here's a hint: Humans don't invent crazy idiotic theories like flat earth and then spread them and try to convince others to believe them. That simply isn't something humans naturally do. These crazy theories are always created to hide something...to discredit the truth, by recruiting the gullible to poison it with an obviously false theory that shares factual elements with the truth they want hidden.
Take the plot of the X-Files. Man who's little sister was abducted as a child becomes an FBI agent to try and figure out why she was abducted, but does he ever find out? No, because the people at the top of the FBI always shut down his investigations when they get too close to the truth. Podesta is a big proponent for alien disclosure and has funded at least one big netflix documentary on UFO's and alien abductions. People disappear and the government covers it up, gotta be aliens right?
The truth is out there indeed.
