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.

I think that there's life out there, except undiscovered. If you have enough planets, there's bound to be more than one that supports life.
