Why Is Anybody Convinced There Is A God?

Again it's not a matter of explaining it better, I accept science and use it in all endeavours, there is nothing that I need to explain with a belief in an intelligent creator. 

I don't know how much you know about Jewish philosophy but they hold God as Unknowable, that is to say all we know of God is the effect that the entity has on the universe. At some point we (you and I) will both agree that we do not know how the universe was created (not implying creation by an entity just it beginning of existence, just the only word I can think of there), and we have to make a leap of decision, was it intentional by an intelligence or was it random by some natural force.  For me it makes more sense given the other metaphysical theories I follow that I treat that force as intelligent. 

Honestly in terms of metaphysics it makes no day to day difference to me, and I imagine that I live my life in a very similar way to you, at the point that the question comes into play it really is just an intellectual exercise.
