BonafideIt's not only cool because there is a lot of potential on mars, but think about the entire universe, if two planets in one solar system have liquid water, imagine the endless possibilities ahead!
interstellar civilization or even communication is hilariously impractical rn
and will be w/o a SIGNIFICANT change to how we understand and interact with the universe and light and stuff
life could exist on mars rn tho and that's cool, but its very obviously a few billion years behind us unfortunately. Regardless, life in some form will be there within a hundred years or so either from us inhabiting the planet or us accidentally dropping off something that grows :(
