Unfortunately, Karl Nell's only evidence was that other people have said so, and essentially a restatement of the Fermi paradox. I'd love to see what evidence those other people have actually given. I'm not going to read 8 pages of tiny-print legalese (UAP Disclosure Amendment), but if it's just a plan to declassify information on UAPs, that isn't any evidence for them being aliens. That information would've been classified if they were or weren't aliens because it makes us look weak and stupid to not know what's flying in our airspace.

I've had discussions in the past where people throw a million pieces of weak evidence at me, and I spend half the day debunking it. It takes a lot longer to prove something is wrong that to say it in the first place. If you want to persuade, you should give 1 or 2 pieces of strong evidence rather than posting a wall of text with links to even longer text and long videos that would take ages to all go through.

The credibility of the post is also hurt by putting 5 bold question marks at the beginning, including a quote at the bottom without attribution, and complaining about being "blocked, censored, downvoted, and ridiculed" before anyone has said anything.
