Why does earth appear to be the center of the universe?

The Earth is where we are, and it is what we deal with in the course of our daily lives. Other parts of the universe are visible, but they are very far away and we rarely visit them. So from a subjective point of view it is perfectly valid that the Earth is the center of our universe. We also understand that objectively, the Earth is not in any way the center of the universe, but is just one planet out of some unknown but very large number of planets. Our planet is very important to us, but is not very important to the universe, as far as we can tell.
