You are seeing half of the picture—the human lies and deception.
Once you can also see the other half everything starts to make sense—which is the aliens are real.
One place to start is Richard Dolan. He is a professional historian who has been working this issue for decades.
Two of his older books that imho are the textbooks for the history of this topic:

https://www.amazon.com/UFOs-National-Security-State-1973-1991/dp/0967799511
If you prefer videos he has a lot of them, some short summaries and some long discussions:

He also created the term “Breakaway Civilization” a couple of decades ago.
Once you “get it” on that concept everything starts to make sense.
I’ll check him out.
I have no problem abandoning old ideas when they have been shown to be wrong. I used to be a big believer in UFOs. Logic has lead me away from that belief but I am always trying to learn more. If not to change my opinion, then to make my argument stronger.
