The Origin of Life According to Melanin

There are diverse theories about the origin of life on Earth. Perhaps it started with an electric spark that generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia, and hydrogen, and over million years, larger and more complex molecules could form. Other possibility is that molecules of life met on clay due to DNA are relatively well preserved in those conditions. Or maybe life began at the bottom of the sea, at deep-sea vents or submarine hydrothermal vents those spewing hydrogen rich molecules. Or under layers of ice, that perhaps protected organic compounds in the water below from UV rays. Or better the RNA world because RNA can create DNA and proteins, and has on-off switch function for some genes. However, scientists calculate that it would take much longer than the age of universe for randomly generated RNA molecules to evolve sufficiently to achieve the modern level of sophistication of the vast biological complexity on Earth today. In other words, it would take forever. Furthermore, synthetic RNA, created with modern technology trying to prove of the concept of RNA world; bear little resemblance to anything anyone has ever isolated from a living system. The finding that all the enzymes involved in genetic code translation have virtually identical cores or Urzymes (Ur -earliest-), suggest simple ancestors (peptides) that evolved to give rise to more complex life forms. However, the main question is simply carried back: How did these peptides originate with so accurate catalytic capacity? Another theory is simple molecules interacting with each other in cycles of reaction that eventually evolved. Or perhaps life was brought here from elsewhere in space, a theory known as panspermia. The theory of special creation proposes that life was created by a supernatural power. Abiogenesis or autogenesis states that life originated from nonliving things, spontaneously. Other discarded theories are the eternity of life, and theory of catastrophism.
