Naaji,
I think what you are saying is that .. God is? We don't need proof? I think everyone here would agree with you. Isn't that why we all hold so strongly to our faith? We KNOW God is.
When things happen in our lives like Lindabee has described, it does strengthen our relationship to God, not our belief that HE is. Suddenly, we see he is interested in us as individuals. We are not just a number. All the promises that we are carried in the palms of His hand, that the hairs on our head are numbered, that He knew us before we were born, ... answered prayer, just reinforce what we know in our hearts, as you are trying to say I think.. we just KNOW that God exists.
