@Little Rik. Something I'm curious about; you've defined how rebirth works in your view for humans... bad; devolve into an animal, neither good nor bad; no change, and good; evolve spiritually in some way into some higher being. But how does it work for animals in your view? Ie how does a dog, say, evolve (in your sense) into a human? What is a higher spiritual state for a dog?... what guarantees it an upgrade, downgrade, or no change? Eg what is a good dog that will be reborn as something 'better', what is a bad dog that will be reborn as something 'worse', and what is a neither good nor bad dog that will be reborn again as a dog?
