Theist?

I was reading this enjoyable article from Ricky Gervais, and was thought-provoked.

I wonder if people like Ricky Gervais themselves are thinking correctly or scientifically.

I used to debate with friends and relatives that Science is great and it proves that God doesn't exist.
That God, as portrayed in the holy books doesn't exist and Science (or logic) can prove that. That its impossible that there is one almighty - who oversees the world... who vanquishes all evil in the world... who can make miracles happen... who washes away people's sins at the instance of touching holy water or offering a prayer... etc etc.

Over years, I realized that there's something else, which is far more profound than debating the form or shape of God. It is also related to spirituality and can not be explained by my current understanding of science.

What do you call the fire inside a man, which drives him/her to overcome all hostilities and emerge a winner? What do you call that psychological condition that lets a batsman thwack a ball for a six in one match and lose form in another match? What is it that makes a person's heart swell when he/she sees the beauty of nature? What is it that makes a person make the right choice?
I'm not sure how to term it. People term it consciousness, determination, form, enthusiasm, realization, confidence, control, love, passion, etc etc etc.

I see a lot of spiritual gurus in India explain this consciousness. That understanding does help the average person overcome his/her own limitation. I believe in that. But often, the same gurus rely on a deity to get their message across. I'm not clear why. Chanting a mantra most definitely won't bring your favourite deity in front of you. But I acknowledge that sometimes, it helps slipping in to meditation.

The confusion or the argument continues in my mind. And I don't have the clarity yet.

A doctor can inspect a brain and declare if its working fine. But he/she can't say if its feeling fine.
