Büllshit.
1. All studies from the past 4 year or so totally refute that. In fact, just recently we found life on Mars.
2. If you mean life that is not a micro organism, sure. Not in this solar system.
The fact that we and we only inhabit the only planet capable of life is basically impossible. There's bound to be another planet that resembled ours in the vast universe.

Edited by CAD1420Z: 4/4/2015 7:57:51 PMNon-earth life, whatever level of development, is a statistical probability/certainty. The more we calculate how many planets that could be garden worlds (or specifically habitable to a certain species, because for all we know slime creatures that breath helium and exhale nitrogen exist), the sheer likelihood of alien life existing skyrockets.
