Life starts in space


Geeklawyer is intrigued by the discovery of organic chemicals in space. It is, he thinks, self evident that life on Earth is sparked by processes elsewhere. In the past it has been suggested that raw elements have been available and which when subject to electrochemistry on the earth led to amino acids and thereby RNA and thence to DNA and thence life as we know it.

Geeklawyer suspects that this discovery of amino acids formed in space is merely the start. Geeklawyer has the intuitive sense that RNA, and perhaps even DNA, is floating in space. This will not inevitably be the result of spontaneous production in the emptiness of space, but rather chemical evolution on various planets which are then distributed into space by ejecta such as volcanos or cometary impact. These ejecta will then float through the galaxies until they settle, like snow, on passing planets. Most of these planets will be barren or hostile, but in rare instances there will be a receptive environment: for example our own Earth or Mars. Here if the environment remains positive then such chemicals will survive and procreate. It would not surprise Geeklawyer to hear that cellular blooms found, on some distant day in the future, in the ice covered subsurface oceans of Saturn moon IO exhibit significant DNA coherence with DNA found on Earth.

Sadly this will be probably be some centuries from now and Geeklawyer expects to be dead by then. Unless, that is, the painting of him in his attic adopts his degenerative countenance.
