And do believe that I, this random guy on the internet has a soul
I personally don't believe that I anyone else has a soul. From my standup I don't se any reason to believe that our consciousness and our so called "soul" would be any more then something our brain is making up.
Yes and no. The idea that people are temporarily possessed meat puppets is just silly. But I do think there is something intangible that makes a person who they are. That we don’t have souls so much as we are “souls”.
Ug, I really don’t understand it enough to answer the question… it is sort of like the ship of Theseus. If we slowly replace, upgrade, or even modify each part of the ship, it remains the ship of Theseus even when every piece is replaced. There is something intangible left that makes it the ship of Theseus, makes all the old bits still part of it, and incorporates the changes into it as well.
That would be the consciousness that lives in the meat puppet, the experiences of life shaping it the whole time.
Not a soul, per se, just an accident of physics. Something as yet unquantifiable, but definitely something. Quite possibly something involving quantum physics, which would explain the difficulty in determining what makes us, us.
We've discovered that a number of life forms appear to use quantum effects in some way, the ones I remember were navigation oriented (ba dum tish). Having existing examples of biology making use of the quantum world makes the idea much less of a stretch.
