Actually there is irrefutable proof if you are open to it. Lets review the evidence.

1. If I remove your source of oxygen you will lose consciousness and die in about 3 minutes.

2. If I remove your source of water you will lose consciousness and die in about 3 days.

3. If I remove your source of energy (food) you will lose consciousness and die in about 3 weeks.

All of these are explainable, and perfectly consistent, with known laws of chemistry and physics.

Assuming a spirit exists there is no known information, biblical or otherwise, that explains why depriving a spirit of oxygen, or water, or food, will cause it to depart in accordance with known laws of chemistry and physics.

Why should a spirit be affected by a fungal, bacterial, or viral infection? Why should a spirit respond, in a predictable manner, to chemical alteration of a protein or a nucleic acid? Again there is nothing in any holy book that supports what is easily explained by the known laws of chemistry and physics.
