Or we are extremely rare. I suspect that biological planets are rare, and those with the sort of "bio-exuberance" seen here are even rarer. It could be that statistically the nearest ETI capable of observing the universe is 100 million light years away, or if in the Milky Way 100 million years in the past or future.
