It discusses the mystery of how life emerged on Earth, and how scientists have some theories about how complex cellular life was generated around 3.7 billion years ago. Scientists believe that amino acids existed in great abundance in the Earth's early years and contributed to the creation of the first cell. Experiments, such as my favorite lol “Miller-Urey Experiment”, simulate the conditions of Earth's early atmosphere and have produced organic compounds such as amino acids. Proteins are the building blocks of all living organisms, and understanding how they formed is crucial to understanding how life started. Although hundreds of different amino acids may have been present on the early Earth, all living things rely on only about 20 of these compounds. It’s Science man…:)
