Thats a loaded question. It assumes souls exist in the first place.
If you can provide proof that souls exist and not just some religious concept then I have no reason to entertain that question.
Jump on me for this one, but your soul is your essence, how you carry yourself.
I believe we can speak without speaking, see without vision, and we can sense things within each other.
Your soul is your collective being, since birth.
All your choices, thoughts and intentions generate a "vibe" that is evaluated sub-consciously by people you interact with.
Does your soul exist? I agree it is a loaded question since it's a concept.
But I argue that if you can agree with what I stated above, than arguing against it's existence is moot.
Your soul is what the living will remember after you are gone, much like Jesus.
Your fulcrum for belief is hinging on proof of Jesus but with AI, you can't trust a photo anymore. So, I can't prove the existence of anyone who's dead without testimonies of the living.
Those testimonies have survived 2000+ years.
Or, the people long ago, were obsessed with writing stories about a character who strived to live peacefully, without sin. Could be their reaction to living amongst barbaric morons
