I have actual, verifiable, proof that you are in a precarious position to say that God does not exist.
1) Science and the scientific method cannot disprove the existence of something, nor, conversely, prove the non-existence of anything.
2) Many modern events, which are verifiable by eye-witness accounts, occur in which supernatural forces are at work. Explain these how you will, they positively give evidence for the existence of unseen beings which may or may not be within our ordinary realm of reality. I have personally witnessed numerous such miracles.
3) One such miracle, when I was young, depressed, and thinking of running away from home: I sat out in the car in the cold of night and just cried. I didn't know if anyone cared, and I doubted if there was a God who cared either. There was a particularly dark patch of sky, with seemingly no stars in it, so I said, "God, if you exist, and if you love me, send a shooting star right there." Then I waited. A few seconds later, I saw one of the brightest meteorites of my entire life, and it fell in exactly that patch of sky. Before I had even had time to process this mentally, a second one, equally bright, fell in exactly the same spot! God was telling that He exists AND that He loves me.
4) God has promised that any who truly seek Him will find Him. Have you looked?
5) There are several things you could do, according to the Bible, which you seem to despise, that would PROVE God is not God. In fact, anyone could do these. What's more, some have tried, and failed! God has staked His honor on these prophecies, and so if you can do just one of these two things, you will prove God wrong: 1) Rebuild the ancient city of Tyre, or 2) Live in ancient Babylon! That's all you would have to do! Just live in Babylon! You would defeat God by that simple act. I dare you to try!
(Of course, if you die trying, I guess you still wouldn't know that God exists...hmm...)
