Lucky in what way? Being an average sized planet, orbiting an average star, within an average solar system, in an average tiny, tiny portion of the Milky Way Galaxy? If that's your definition of "luck", it might be the most meaningless word conceivable by human minds.True, nothing happened here for a long time, when it did, only one species in millions developed intelligence, that's on a planet that was already extraordinarily lucky.
The size of the universe demands that these conditions have the oppertunity to happen elsewhere. To say that they wouldn't shows a poor grasp of how incomprehensibly vast and ancient the universe is. What is it, 14 or so Billion years? Fourteen million-million years. More than that many stars in the Milky Way alone.The size of the universe does not make it inevitable that this happened twice, it seems like it's the uncomfortable implications that are the only thing that demands that it did.
Even assuming life is freakishly rare, that would still mean there's more intelligent in the universe than there are grains of sand on the earth.
