I feel as though for past lives to be real, the concept of a human soul needs to be real too.
When thinking of past lives, I feel that in order for an afterlife to be real, the idea of a human soul that exists separate from the body and mind has to be real. If souls do not exist, then I am failing to see what part of humanity survives to go from one existence to a completely new existence. The concept of a past life then does not seem to be plausible to me.
Is it accurate that there needs to be human souls for there to be past lives? Or am I missing something here?
