One of the claims often made to illustrate how science has refuted Christianity is the size of the universe. The Bible teaches that the human race is so important to God that he sent his Son to Earth to die for us. But modern astronomy has shown us that the Earth is just an infinitely small speck in an infinitely large cosmos. How can we think we have any importance in light of this?

There are several ways to respond to this challenge. You could point out that the Bible doesn't teach anything about the size of the universe. You could argue that the ancients and medievals thought the Earth was one of the smallest objects in an unimaginably large universe. You could ask what something's size has to do with its importance or value to God. I wrote a three-part series on my blog on this issue, so here are the links; feel free to check it out:
