Or it could mean that the building blocks of life are "universal" under the conditions needed to form them, and that they formed elsewhere, as well as on earth.

parallel evolution rarely occurs on Earth.

Oh and thanks Scott for getting the avatars back.

Some comet with mountains or something.

That doesn't mean that amino acid formation isn't an inevitable occurrence when the "perfect storm" of conditions exists. Merely finding glycine on a comet doesn't prove that life existed/exists elsewhere. Or that life only started because asteroids seeded the earth with biological material. I mean, how many asteroids would have needed to hit the earth's oceans, and in close proximity, to form the first organism? And how did those compounds form, wherever they came from, if they came from a life-producing planet? Furthermore, many biological compounds need to be synthesized; they don't just appear out of thin air.
