Also, show me the species on other planets. Far as we know there aren't any and none of the planets seem to be habitable. Stop living in fantasy land.

You surely don't mean that no other planets could be used to sustain life with technological assistance?

Mars has water, accessible nitrogen (HNO3), carbon (CO2), hydrogen (H2O), oxygen (all of the above)... technologically assisted humans could absolutely inhabit mars.

>>Also, show me the species on other planets.

Exactly, lets go there and see for ourselves.

Send robots.

Even from that point of view, Mars is even more hostile to life (as we know it) than Earth.

Mars is just a placeholder for an alternate home to earth.

Most technologies developed for these missions will be reused or new ones will built on top of them.

Yes, I understand Mars is a placeholder. But I life in a new planet that must be terraformed is even worse and more hostile to human life than, say, colonizing a new continent. Or building undersea colonies, like someone else said. Even the colonization of an Earth-like planet would be almost impossible, and we aren't aware of any nearby.

We would be going to a less inhabitable place, while taking all the problems of mankind with us. I must echo the grandparent post: Earth is not the problem -- we are.
