I think the research done into reincarnation and those who remember their past lives is very interesting. Lots of compelling 'evidence' on the subject, I find it very difficult to outright dismiss. I would say it's the logical explanation.

A greater or collective un/consciousness is coherent at explaining both perspectives, at least the way I have understood it. The body isn't a container for the soul, it's the physical expression/manifestation of the soul.
