After rreading your commment I have come to the conclusion that you are a closed minded little girl. You really think our goverment doesnt have enough money to do what they need?
1. We pay taxes ($$$)
2. I believe that other life forms would love to visit earth for the same reason that we would like to go visit them. To know what else is out there. To analyze our way of living, to have a new home (ETC.)
Cause how can we be the only plant in not only our galaxy but the entire universe that can with hold life. Have the right climate, atmosphere, and to be the right distance from the sun.
Theirs got to be more out their. We cant be the only ones.
