Extraterrestrial life

I think there must be life somewhere else, but as for it ever visiting Earth, pfft I soo doubt that. On the comment about our military, well really one of the major reasons for space travel, visiting other planets, is because we are running out of room on Earth and even more in regards to resources. Why do you think people are so focused on Mars and the exploration of other planets, sure there is that exploration thrill, but the government doesn't care about that, right? I may be a bit biased at the moment, I saw "War of the Worlds" recently and in that movie the "aliens" are invading to take our resources, which include blood (in the movie *rolls eyes*). Humans are unique in there disregard for nature and other species. Take for instance in the movie "The Matrix" Mr. Smith says to Morpheus that humans are like viruses, rather then staying contained, they spread. I took Model United Nations (MUN) in high school, I studied and made speeches on all kinds of global issues and found that the root cause of all them is overpopulation. Quite frankly, we reproduce way to much, really the only thing that could be done would be to stop having sex, but people "can't help themselves". I think its obvious who is to blame. Everyone that "can't help themselves". pfft. That was a bit of a tangent but so is every rant I ever have; it all relates though. Why are we exploring? For more resources. Why do we need more resources? Overpopulation. Why? Keep asking questions all day and you still won't get anywhere. Is there life elsewhere? Probably. Are they anything like us? You'd hope they aren't; or else it will be a war, either them or us, right? We gotta learn to share. But I don't see that happening...
