If you look through all the different cultures. Right from the earliest, earliest days with the animistic religions, we have sought to have some kind of explanation for our life, for our being, that is outside of our humanity.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

I was even accused of teaching the chimps how to fish for termites which I mean that would have been such a brilliant coup.

Is it not possible that the chimpanzees are responding to some feeling like awe? A feeling generated by the mystery of water; water that seems alive, always rushing past yet never going, always the same yet ever different. Was it perhaps similar feelings of awe that gave rise to the first animistic religions, the worship of the elements and the mysteries of nature over which there was no control? Only when our prehistoric ancestors developed language would it have been possible to discuss such internal feelings and create a shared religion.

We have turned away from the natural world. Instead, it's all about money and power.

We find animals doing things that we, in our arrogance, used to think was "just human".

What makes us human, I think, is an ability to ask questions, a consequence of our sophisticated spoken language.
