No, and let me tell you why. (1) Mars doesn’t have much of a gravitational field (only 38% of earth’s) so it can’t hold on to a dense atmosphere and it is unlikely that humans can remain healthy is such low gravity. (2) Mars doesn’t have a magnetic field to deflect deadly radiation from space. (3) The soil on Mars is full of perchlorates (think rocket fuel).
And that’s OK because we have a world that was created just for us. Isaiah 45:18 – “For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD, and there is none else.”
All excellent reasons why terraforming will remain science fiction IMO.
