Staying on Earth just because we evolved here would be even more absurd.

Travelling to Mars might be  dangerous. but living there would be fine, 
once we'd engineered a safe environment for people to live.

We might well be able to engineer people who could live there safely - 
evolution has yet to come up with an error-detecting genetic code that 
lends itself to error correction. but intelligent design could do better.
