Is there life on other planets?

Considering the number of stars in the universe, even if only a few of them have planets, it seems highly unlikely that Earth is the only planet supporting life.

However, it seems that all life on Earth evolved from a single ancestor, suggesting that abiogenesis is extremely rare. It is possibly so rare that it has only ever happened once anywhere?

There's the Fermi Paradox for you. And why the human race can be so frustrating at times we just all bicker and squabble when we could be the highest intelligence in the universe and what are we really doing with it?
