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?

I think given the number of stars in the universe as 100 octillion. We know, as we exist, that the probability of life starting is greater then zero. I think that even if the actual probability is between zero and a stupidly small number, with 100 octillion stars around, then I cannot help feeling that life, it could be assumed, is likely to have started round at least other one star.
