Theres no hard proof that life can exist anywhere else in the universe, other then "we live on Earth, and thats a planet! Life on teh marz!". And while its nice to dream, until we actually find hard evidence of other life (and Im not talking about microbes), Ill have to wave the "You're not a scientist, don't pretend like you are because you watched a special on Discovery Channel" flag.
This announcement could be anything. Plans to start working on a warp drive (which I expect would end with catastrophic results), announcement that Einstein was wrong and it is possible to travel faster than light speed, a deep space telescope, a planet that's comparable to Earth in location and may hold water... Or something completely stupid thats more than likely a waste of everyones time except for like 4 scientists.
Either way, until I see hard proof that we are not alone in the universe, Im just going to imagine we are. The chances of life occuring is so low, SO many things had to be done, and be done RIGHT, that even the vastness of the universe doesnt yeild anything like Earth.
