Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
Even if we found a planet in our nearest star, on our current technology it would take us 50,000+ years to get to, give or take, so what’s an extra 10 or 20 thousand years at that point.
So that’s a problem. How do we get us, or anything we build that far and that long away?
