Fermi's Question (from Wikipedia): The extreme age of the universe and
its vast number of stars suggest that if the Earth is typical,
extraterrestrial life should be common.

The logic may be informal, but it is certainly there. The paradox
disproves the assumption that the earth is typical. We don't know how
common double planet systems are, but TerraLuna is certainly the only
one in our solar system. The chance of formation of a double planet may
be vanishingly small.
