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?

That's very profound. I agree; it would be extremely unlikely Earth would be the only planet supporting life. I believe life is abundant in the universe. I also think abiogenesis doesn't exist at a quantum level. Even the amino acids which were the building blocks of life on Earth, had a foundation of which science may not yet be aware.
