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?

Considerring the concept of infinity, there could be a parallel universe almost identical to ours.

@samueltyler2 In a truly infinite universe, every probability becomes a certainty.

@samueltyler2 they think they've found two. Apparently universes are arranged like beads on a string. They can see the temperature change in the blackbody microwave readings.
