The claim under examination: reality includes something beyond the purely physical, and perhaps a mind behind it.
Standard · preponderance of the evidence, not proof
The verdict
Strict materialism is plausible but not established. That reality includes something beyond matter is a live, serious possibility. That this something is a personal God is possible, not established at this stage.
If you read nothing else
We cannot argue "science can't explain it, therefore God," and the reverse is just as false. Several features of reality remain real clues, naturalism has serious answers, and theism carries real costs. Neither side gets to declare victory. But the supernatural cannot be ruled out by definition, so the investigation continues.
