I am a scientist BUT I believe in God because of one simple reason: there are many things in life that science is not able to explain. Atheists may argue, that it's just that science has not been developed enough to explain such things, but has managed to discover certain rules that make things stand where they stand now, right? For example, the way sun heats our planet, the way gravitation works, the way our planet circles around, and so on. But what if there was a minor deterioration from those rules? Our planet would jump right to the sun and immediately burn down. So what is that superior power that keeps those things in their places?

Call it GOD, Jesus, Evil or just a superior power. I call it God. I don't think there is anything wrong with such assumption.
