Intelligent Design Origin Of Life

Could life have started in the depths of the Earth? It’s controversial.

The question originated with Cornell astronomer Thomas Gold in a 1992 paper and was developed in a book, Underground (2019) by Will Hunt.

As science writer Ross Pomeroy explains at Real Clear Science, much of the controversy revolved around claims made by Hunt that oil and gas dated to Earth’s formation…

The main effect was to encourage looking deep in Earth for life forms. If you don’t mind that they are all microbes, it has been a rich haul:

Microbes have been found as far as 2.8 kilometers underground, munching on a range of minerals for “food” and generally subsisting at a much slower pace compared to life up above. Some are so different from surface microbes that they’ve garnered a catchy nickname: “intraterrestrials”. Crucially, in regards’ to Gold’s bold hypotheses that deep microbes could have started life and may exist in the interiors of far-flung planets, scientists have found a bacterium that seems to exist totally independent from Earth’s surface. Candidatus Desulforudis audaxviator was found under a deep gold mine in South Africa and exists at temperatures as high as 140 degrees Fahrenheit in the absence of organic compounds, light, and oxygen.

Talk about an extremophile deep in the Earth! Trouble is we don’t know that life started out like that. It could just as easily be that one late-arriving microbe could inhabit that territory but nothing else could.

Some hope to find evidence of life forms like audaxviator on exoplanets.

    Claiming that oil was there from the start is definitely out of the mainstream.

    Oil is a complex fermentation product, not a basic mineral. There’s an active argument about whether all oil is “done”, or still in process, but the latter seems more plausible. Wine and cheese are never “done”, we just halt the ferment at various points to get various tastes.

    If he wants to claim that oil was here at the start, he needs to account for the fermentation. Was oil made elsewhere and transported here, then injected????

    The idea of life starting anywhere by accident is controversial! I know scientists think that everything has to have a scientific cause so they are strong believers that it did, but as sincere as their faith may be, it doesn’t make it true.
