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?

Well it depends, most people envision alien races as highly intelligent when in reality alien life could range from many different sources like plants, non self aware entities, all the way to self aware beings but who says their smart just because their self aware, though they could be intelligent.

So aliens most likely exist but may not be what we envision them as, and I think that's more possible than how we evolved.

@SatanBurger I did mean life in any form, not necessarily intelligent or humanoid life. It just occurred to me that, if abiogenesis were reasonably common, we should find more than one evolutionary line on Earth.
