But they knew about extraterrestrials and spaceflight, so why didn't they ever just think of asking anyone for help?
I don't remember this being established in the episode. Could you let me know when that's shown?

Anyway, even if they could evacuate to other planets, they'd produce a paradox in their own history if they don't evacuate the population to their own history. Closed time loops are like that.
