It depends on what time scale you're talking about. Here's a Kurzgesagt video that describes how to do it over the course of millions of years: https://www.youtube.com/watch?v=v3y8AIEX_dU

That's a loooong time, obviously, but it's not "theoretically impossible"

Sure, but it assumes technology we don't remotely have. Maybe I should not have used the word "theoretically" here. It's just ridiculous to seriously consider it at this point.

It is nice to think about it, of course. But I just don't get how people support wasting so many resources into sending people to Mars where it's basically useless (though exciting, I get it!) and we have much bigger problems to solve on Earth (e.g. the survival of our species in acceptable conditions).

I think the word you misused is "impossible," not "theoretically."
