Describe the Theory of the Origin of Life?

What is the current best theory for the origin of life?

• Give me some details on how life came to be. Evolution alone doesn't explain the origin of life, only the current complexity. What's the best theory we have at the moment, with the most promising evidence?

• Answer:

  All the necessary organic molecules such as lipids, carbohydrates, proteins, nucleic acids, vitimins, minerals, and all other materials found in a cell came togeter in protoplasm conditions, which is the condition necessary for life. The collection was struck by lightning and gave rise to simple unicellular prokaryotes like bacteria that had no membrane-bound organelles. The only membrane it has was the membrane that covers the entire cell. It is believed that Mitochondria and chloroplasts existed on their own as organisms because they have their own DNA. The theory is that they developed a symbiotic relationship with bacteria and lived inside the bacteria until they merged into the same organism. This gave rise to the first unicellular Eukaryotic Protozoa. The protozoa that had chloroplasts became algea and other plant-like protozoan and those with only mitochondria became animal-like protozoa and there are also fungi-like protozoa. The unicellular individuals that replicated through clonal propagation eventually collected and became multi-cellular organisms. algea later evolved into plants, animal-like protozoa evolved into animals and fungi-like protozoa evolved into fungi. Later on, cells started to specialize into different tissues and became organs. sexual reproduction evolved over time when reproductive organs started making special reproductive cells like gametes. Bacteria can use several types of chemicals for metabolism from hydrogen sulfide to nitrous oxide to salt. The bacteria that evolved into multi-cellular organism were most likely aerobic bacteria that use oxygen.
