Lets say we get off this planet and go to...lets say Mars, being the best choice so far. After living on Mars and transferring Earth's "excess" population there, we have a great understanding of living and traveling in space. Then we make a ship that can go VERY fast and VERY far (antimatter engines, solar sails, HyperSleep....blah blah blah). I have a strong belief there is intelligent life somewhere out there. I don't think they have discovered us though. -What happens when we are the aliens? How would we conduct ourselves?
