Sure. You tell me what public test would convince you of the non-existence of God, and I will do it. I can give you several tests that would convince me that the universe was created by an intelligence. Here's a couple:<quoted text>
How about you disprove god.
1. A collection of millisecond pulsars at varying distances, but that appear to be synchronized at Earth that spell out YHWH in the sky.
2. A copy of the Hebrew version of Genesis encoded in the DNA of all humans.
See? Both of those would be unambiguous signals that the Biblical God created either the universe or life on Earth.
Now, it is your turn: what observation would convince you that you are wrong?
