Not sure what to think

I've heard / seen / read lots of things about the government how they lie, cheat, cover-up, secret missions, etc.

I don't know what to think anymore. There's lots of evidence, you just have to look. The stealth fighter / bomber projects used the idea of UFO's to cover-up the test flights. It's smart, I would do it too. With this in mind, why wouldn't the government also lie and cover-up anything to do with ET's?

Will Smith and family visited President Obama in the white house. Don't ask me why. They're somehow related? IDK...

Jaden asked Obama about aliens. Obama's response:
'OK, I can neither confirm nor deny the existence of extra-terrestrials," Smith quoted the president as saying, "but I can tell you if there had been a top-secret meeting and if there would have had to have been a discussion about it, it would have taken place in this room.'"

If this footage was real and apollo missions 18, 19, 20 did in fact happen, I'm now terrified to the core. I know for a fact that most of the apollo missions had some kind of accident or malfunction. What other lies are true?
