I found an interesting piece of reading at http://www.everystudent.com/features/isthere.html which goes like this :

Does God exist?
Here are six straight-forward reasons to believe that God is really there.
By Marilyn Adamson

Just once wouldn’t you love for someone to simply show you the evidence for God’s existence? No arm-twisting. No statements of, “You just have to believe.” Well, here is an attempt to candidly offer some of the reasons which suggest that God exists.

But first consider this. If a person opposes even the possibility of there being a God, then any evidence can be rationalized or explained away. It is like if someone refuses to believe that people have walked on the moon, then no amount of information is going to change their thinking. Photographs of astronauts walking on the moon, interviews with the astronauts, moon rocks…all the evidence would be worthless, because the person has already concluded that people cannot go to the moon.
