The miracle of a planet that substains life is uncalculable. It could be quite possible that we are it.
Actually it has been calculated and that is why SETI is listening...
Even the most pessimistic estimates have earth-like planets in the hundreds of millions just in this galaxy. Statistically, half the civilizations would be older than humans, most much older. It isn't much of a leap to think the same tech that would produce faster than light travel would also bring faster than light communications. We just may be deaf... ;)
