How can you seriously ask a question like that?
We’ve never even found a microbe or a fossil of a microbe anywhere in the universe except here on Earth. Now you’re asking can ETs take us somewhere else to start anew?
I guess you are assuming that there are extraterrestrials out there somewhere who somehow can go back and forth across many light years to save us from ourselves.
No one is going to take us anywhere. No one is going to cross the vastness of space to save us from our own undoing. If we don’t save our own planet, no one is going to come and save us.
That’s not Hollywood. That’s just the way it is in reality.
At this point we’ve not ever seen real evidence of anything living anywhere but here on Earth.
