Why Are We Here?

Where does life come from, and why is it what it is?  These are great mysteries.  Even so, Darwinian theorists tell us it is nothing but a mechanical process that in principle is entirely explicable by reference to biochemistry, and thus to well-known properties of matter.

The key, they say, is random variation and natural selection.  Parents and offspring differ in random ways because of mutation and shuffling of DNA molecules.  As one generation follows another, variations that happen to facilitate survival and reproduction accumulate, since offspring that possess them live longer and have more descendants.  As the process goes on, and more favorable variations become fixed, distant descendants diverge more and more from the ancestral type.

There is no evident limit to the process, and it has been going on for billions of years.  With that in mind, it becomes imaginable that a single-celled organism that started sticking together with others in clusters, because that somehow helped it survive, should eventually develop into something like a primitive worm, the worm into a fish, and the fish ultimately, after hundreds of millions of years, into you and me.

The story is a compelling one, a great deal of biological evidence is consistent with it, the mechanisms it relies on undoubtedly exist, and scientists like to explain complex things by reference to simple mechanical causes. ...
