If aliens exist, it doesn't matter unless we are having some sort of interaction with them, which given how we interact with each other, is likely to be violent, and end with us getting killed. Given how we haven't been vaporized yet, I don't think we have had that interaction.

I can't prove nor disprove the supernatural stuff, so I just ignore it.

All of this stuff is used as a distraction from the real shit the government does.
