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?

The verdict is still out if there was ever life on Mars since liquid water and buried organic matter was discovered. And there's some other spots in our solar system that seem to have some of the prerequisites for life.
