several things to put in is that if any alien life form did travel millions of miles why would they? what is on our planet that isn't on any other we have seen so far? a perfectly balanced atmosphere! we have just enough of everything to keep carbon based lifeforms alive and well! That would be the only reason apart from the obvious making friends with us. If they did indeed come for the atmosphere we wouldn't be able to share it as our world is only just big enough to home all the human beings. If they wanted to use our atmosphere either we would have to move or they would have to go away. obviously we both would want the planet and there would be politicial arguments between humans and aliens. at one point one would strike. then it would be the mother of all wars. a nuke wouldn't work because to be able to travel through space you would need protection from nukes. we would have a hard time survivng. then it would probably go to biological war, or viruses. we would all die off slowly until we found the antidote. the only way at the moment they could beat them is by using an effect where thousands of projectiles are launched from the earth at once knocking off the orbit of any space craft and probably making them leave...
does that clear everything up?
