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.
No and no. Physics is pretty thoroughly buckled down at this point, leaving only some very extreme situations unaccounted for, and it doesn't really provide a way for us to not be made of meat.
That goes for any other form of mind-body duality and as a result any afterlife, as well.
