Yeah I too question the idea of outer space ever since I decided to take a look at the flat earth videos.
I'm udecided on the matter because it's so crazy and yet that curvature formula of the earth is obviously wrong.
On the other hand I used to be almost convinced in the ancient alien theory. I though we had visitors from other planets in the past and hence gigantic structures were built back when they couldn't possibly have the technology.
Both ideas seem counterintuitive.
But I think you're right in the sense that the idea of space is in some part running away from your problems, unhappiness.
And it's also like flat earthers say a way for scientists&rulers to say look we have to search through trillions of light years of space to find out if there is a God and until then listen to us.
Then again like you said we might me missing out on a huge party on some planet somewhere :):):)
