Should you go to Mars? ft Bill Nye

You are an inspiration! I think Mars is important, as you say, for exploration and discovery. I am concerned with the aspect of extra-planetary colonization as it is probable that the most hospitable environment for humans and other Earth species is well outside the solar system. I imagine a blue planet millions of light years away with some form of sentient life. It would make sense, in that case, that they would see Earth as it was (for example) during the time of the dinosaurs.
