> That's why I never understood sci Fi nerds obsession with outer space

I'm sure you do understand it. I mean, sure, the other things you mention are also interesting, but mankind has been awed by a starry night's sky since we were able to look up. We gave names to the arrangements of bright things in the skies and imagined gods in them, and navigated by them. The are awe-inspiring.

It's really a human thing, not a scifi nerd's. It's impossible not to look at the stars and wonder. It's human nature.
