Absolute undeniable evidence for existence of God?

[Anomalocaris]

If "Hello, my creations" in block letters a billion light years tall is detected etched into the temperture patterns of cosmic background radiation, I might treat that as evidence in favor of the POSSIBILITY that a being both aware of us and at some level care for us heavily menipulated, but not necessarily created, the universe.

However, the very fact that I am moved to this conclusion by EVIDENCE tells me the being in question is natural, not supernatural.
