I met my father yesterday for the first time in 10 years

And he told me he was a flat earther because of this video in specific. It shows that pilots have to sign a contract saying they cannot release this to the public and one man video recorded it and ended up disappearing and it shows that the sun is not in space and neither of the other planets and the Sun is actually within the clouds of the sky and it's below the horizon. I have no idea what to think when I saw this video. [youtube=https://www.youtube.com/watch?v=XQKS0kvTWzQ]
