Abstract It is generally thought that the Universe started with a big explosion (Big Bang) approximately 15 billion years ago. Hydrogen and helium were formed within the first few minutes, while all the other chemical elements are the by-products of stellar evolution that are added to the interstellar medium through the supernova explosions of the larger stars. Carbon, Oxygen, Hydrogen and Nitrogen, which constitute about 98% of the biomass of the Earth, are also among the most abundant chemical elements in the Universe. A seemingly unique combination of the fundamental laws and constants of the Universe made possible the origin and subsequent slow evolution of life.
