I like the idea of multi dimensional souls that live a number of lives. I am kinda open to what the universe may bring and deeply believe things happen for a reason.
However I am also an engineer and I deal with numbers, facts and information.
Lets say 10,000 yrs ago the world's human population was 100 million. Today it is something like 6 billion I think. Where did those 5,900,000,000 souls come from over the last say 10,000m yrs? What were they doing 10,000 years ago?
Logically you'd see souls cloning to keep up with population growth rather than greedily grabbing multiple terrestial exitances?
Too concrete I know ... I prefer the concept of multi dimensional souls 8))
