I realize that this all might sound a bit far-fetched but just because we believe it to be impossible for such a creature to exist does not make it so. Alien astronomers somewhere are certainly saying the same for carbon-based life. I applaud them for it. I'm sure all of us would have no problem admitting that. I just wish that NASA would at least embrace the spirit of this sort of discourse.
Space is vast and with it, the possibilities for life.
It's always surprised me that there haven't been more terrorist attacks against the United States. Considering the amount of countries that dislike the US and the ease at which a bomb can be placed, it seems we should count ourselves quite lucky. Either that, or the CIA actually does some good. It's probably a bit of both. Anyone can walk into, say, National Airport and check a bag.
