From Fox News....

Very interesting, but perhaps we're 'splitting hairs' here. To begin with, there's no habitable planets within a radius of 18 months by spacecraft from Earth.  Secondly, unless our ecosystem spawned these things, and that's going to be difficult to prove without extraterrestrial comparisons, then these tough microbes may very well exist elsewhere in the galaxy and Universe, and we may not, in fact, be the cancer that's about to kill the whole shebang like we're doing here with mother Earth.

Star Trek and Star Wars are very thought-provoking, and NASA is fascinating, but the truth is that in the whole history of the Earth, less than 545 people have ever been in space. Definitions vary, but the vast majority of those have only been in earth orbit. The point I'm creeping up on here is that 543 out of a population of 7,233,624,250 is not very favorable odds for you getting into space, even just orbiting our planet. Going anywhere else, and actually staying alive to arrive there is a whole other story. The technology and the financing for which continues to elude us.
