I was going to make a joke about aliens from foreign countries; however, I have seen this done entirely too much on various topics on other forums when aliens are mentioned, and it really is not that funny. Therefore, I shall refrain from making a corny joke and will instead answer seriously.
I choose to believe that some form of intelligent life, other than myself, must exist somewhere in this vast universe as I could not have been born of nothingness. Seeing as it does not exist on this planet, it must be somewhere else.
