Why Do You Want Earth? Why do aliens want earth? There ARE other plants out there. Why do you have to be so greedy? Why do you want earth? You are going to destroy all the buildings, that will be a lot of work. You ARE going to kill us all right? Yes, so if you do, what's the point of coming to earth? You had your own planet and you should be happy with it. What's the point of coming to earth, when we are humans. Is it that you want us? Stop being greedy, and be happy with the plant you already have. Cause your home can be destroyed before you can say your full name. Why do you want earth? When you have your own home.
