Aliens, Where Are All the Extra Terrestrials?

The universe is 90 billion light years in diameter, there are at least a hundred billion galaxies. This means that there are trillions of possibly habitable planets. These other life forms may very likely not be in our neighborhood. They might be in a different neighborhood. And the reason that this sucks so bad for us is because we will probably never get to see them,. Even if we have great technology, because the universe is expanding.
