    In 1953 Stanley Miller shattered the vitalism belief by replicating the conditions on a primitive Earth and thereby beginning the belief in mechanism.

    OK- if I were to suppose that all life on Earth was totally destroyed today - everything - even the organic molecules that make up life such as sugar, proteins, cellulose, etc., were destroyed. In other words, today's Earth would have just the inorganic compounds that exist on all planets - most likely spinning around all stars - salts, gases such as ammonia, carbon dioxide, water, etc. There would be no organic compounds on Earth - just rock, water, sand, minerals - much like the nature of Earth several billions of years ago. now assuming that would happen, explain in detail why you believe that life could or could not spontaneously arise on this Earth today as opposed to what happened several billions of years ago on Earth, according to mechanism.

    Living organisms did arise from an environment of inorganic compounds, so I don't know why it can't happen today under similar conditions. Of course, it all took billions of years to evolve.

    According to the current model, it is believed that the basic chemicals from which life was thought to have formed are methane (CH4), ammonia (NH3), water (H2O), hydrogen sulfide (H2S), carbon dioxide (CO2) or carbon monoxide (CO), and phosphate (PO43-). Therefore, as long as these initial chemical reactions can take place from the available inorganic compounds, then the foundation of life is set for the formation of living organisms. Let's not forget that all compounds, whether organic or inorganic, are composed of the same elements, and chemistry is something that happens all the time. Inorganic ...
