Because of the distances involved the further we look into space, the farther back in time we are seeing. For every light-year away an object is, a year farther back in time is how we are seeing it. So an object 2000000 ly away we are seeing as it was 2000000 years ago.
@evilscientistca when you think about it, if there is any life out there, and it developed concurrently with us, we won't see it for a very very long time and when we do there is a possibility that it already has burned itself out, but we won't know for a long time after.

So what you're saying is, the possibility exists that there was a galaxy far far away and a long time ago there could have been aliens with advanced civilizations? Sounds good to me.
