Mix together 95% of the ingredients of life which are Carbon, Nitrogen, Hydrogen, Oxygen, Phosphorus and Sulphur and try to duplicate Mother Nature’s results. Life on Earth started when rainwater accumulated on Earth as it was cooling. When Earth cooled to about 30-35 degrees or so, rainwater and sunshine became the vehicles of life.
When Earth’s amino acids and alkaline minerals come together in the presence of rainwater, and their pH changes, and nitrogen gas is released. When nitrogen gas is introduced to rainwater in the presence of lightning, air, and 35-degree sunlight, a photosynthesis process forms solar protons that reach Earth and forms fungi and algae. These were the first forms of life on Earth.
This evolutionary scenario can be carried one step further by presuming that the algae, after many years, acquired a vegetarian parasite. The vegetarian parasite then contracted a carnivore parasite, and with more time, the rest is evolutionarily possible.
Oil is a renewable, natural resource produced from rotting vegetation and animal life. As all living organisms perish and their hydrocarbon remains dissolve and gravitate deep below the surface of the Earth they become our energy source of today-oil and coal.
