There is a cool animated explanation and that is one of the steps. https://youtu.be/HpcTJW4ur54

Short answer is we would need to to Teriform mars but one downside is that a disease could wipe out a whole species and throw off the balance. So it would be doable but difficult

Oh, thank you! That is a much more interesting question. I’ll admit that I don’t know enough to ask the right questions but I find space so interesting.

This is dope. Can someone explain tho. If water is in asteroids which is H2O… wouldn’t that mean the O has to come from somewhere else. I get that it is most likely formed from nuclear fusion and an exploding star.

But that would mean these asteroids that form could have landed all over and there should be oxygen on multiple other planets.

So like more evidence that life should be on other planets correct?
