Spirit is an inherently religious concept and cannot be proven either. The burden of proof is on the person making the claim and you literally cannot prove that exists. We can prove that consciousness stops at death by observing that brain activity stops. This make believe gives con artists a way to rob us and turn people against each other. Religion is memetic cancer and does not provide benefit.

I appreciate that you don’t believe this stuff but it’s still bad to support it. The proverbial devil doesn’t need an advocate.
