'God' is another word for 'immortal'. Across its long history humankind has deified most of the things around it that has seemed, to its impermanent eyes, to possess undyingness: the natural world, the sun and stars, the sea and rivers, they were all here before we were and they'll all be here after we've gone.
Now we know better; but it sometimes strikes me as odd that nobody has thought properly to deify the one living process we know to be immortal: DNA itself. Is it the smallness of the object that makes this unappealing to people? We prefer not to confer deity upon the microscopic. We deny DNAity.
