" The thought that a cell (where did it come from in the first instance) decided to split into two and so everything living begun does not compute within my brain."

But it does compute in lots of people's brains, and those who dedicate their lives to finding out how and why these things have occurred and continue to occur can and do tell us. The whole thing is marvellously complicated, but the awe felt when contemplating the natural world and the universe we live in isn't the result of some deep intuitive revelation it's from the mind of a divine creator, it's the deeper understanding that we are the universe contemplating itself and understanding itself. Stop and think about that; we're made of the same stuff as supernovae and planets, interstellar gas clouds and comets - we are those things and we can recognise our own consciousness, contemplate the fact we are a product of a set of rules we are beginning to understand. A concept far more profound and beautiful any religion on earth has yet to get close to; all we have to do is recognise it ourselves and we can develop moral codes that recognise the sanctity and preciousness of all life (even that we don't even recognise at the moment) and the entire physical universe.

We're only scratching the surface at the moment with our infant sciences; it's going to be a whole lot more incredible in years to come. I can't wait.
