Do you believe in God? Why?

According to students who participated in a study by Sheffield University a year ago:

I'm not sure, but it's comforting to believe.
There must be a creator behind such and incredible world.
I just do -- I know it.
I have a relationship with Him.
Because there is more to life than we can understand.
Because there is much evidence to suggest that God exists and that everything is under the control of God.
"Great are those who have believed yet have not seen."
Because things happen for a reason.
I was brought up to believe and later in life have found answers to my troubling questions in my faith.
My conscience exists; how else if God didn't put it there?
I envisage God as a force not as a person.
Every religion believes in the existence of God.
I've experienced miracles.
I feel calm about being assured of salvation.
I have a feeling of a "greater presence."
God is omnipresent in everybody's life.
Hope.
I believe something created all this!
I believe that he helped me in someway or another in my life to come to the U.K. to study
I believe there's someone to look over everyone.
I don't believe that there is nothing more than human existence.
I have to believe in something!
I'm alive, and there has to be something -- though it could be a force of another type.
Intuition.
It makes sense.
It's very hard to explain -- I just do and I always have done.
Look out the window.
Made up my mind after thinking lots about it.
Personal experience, and it makes sense.
Personal experience and upbringing.
I've seen and felt God's presence in my life.
I have seen things that cannot be explained by science.
There has to be a God!
There has to be something!
I used to go to church; I still believe in God, though I don't go to church any more.
What else can you believe in 100 percent?
Who created us then?
Why not?
You have to believe in something
