It feels strange to be a minority within this thread as I myself am agnostic.
One thing I must strongly stress is that true scientific data does not speak one way or the other about the existence of God as it is an untestable phenomenon. Without the ability to control and repeat conditions relating to the entity someone is studying, no empirical information of any kind can be produced. Simply said, God cannot be put into a test-tube.

I must add moreover, that there are some theologians who embrace the concept that God exists naturalistically, and therefore eventually capable of scientific discovery. See Edgar Allan Poe's Mesmeric Revelation
(here).
Science isn't a factor here. The question of God's existence stands by itself. My question to everyone who has answered that they believe God exists, why do you believe this is so?
If the difference between an atheist and a theist is a question of whether we can definitively say reality is guided by a personable force or not, what makes us believe one way or the other?
