You are "looking for some 'proof' of God's existence"? Do you know that the Bible is a proof of God's existence? As you have read the Bible, haven't you noticed how all 66 books of the Bible are united in harmony and purpose? How can this be?
The Bible was written by 40 men, whom were chosen by God to write it. It was written over a period of 1,500 years. Those 40 men who wrote were on 3 separate continents and were all writing about the same thing, the gospel of Christ. In that day, they had no mail delivery trucks, no drop ship planes, no Federal Express, no UPS and no e-mail. So how could it be then, that they all wrote the same things, while on 3 separate continents?
Because as the men wrote, God spoke!
Following are links to many additional proofs of the Bible, and ultimately, God:

If the Bible is true, Christianity is true. In Christianity, faith is required but it does not have to be a blind faith.
