The Big Bang is a theory that the universe began in an initial massive explosion. It is the most popular theory about the origin of the universe. It was first proposed by Georges-Henri Lemaitre. More evidence for the Big Bang was found by Edwin Hubble and Bell Labs.
According to the Big Bang, all the matter in the universe existed at a nano-point, and exploded out from that point. The matter, which was composed of individual protons, neutrons, and electrons, fused together in the massive heat that followed. Gravity took over and attracted small particles to larger particles, forming the first elements (only hydrogen, helium, etc.). These elements in turn formed the first stars. The first stars, then, acting as giant furnaces and through the process of fusion, fused hydrogen, helium, etc., to create the heavier elements, and spewed them out into the stars.
Heavier elements coalesced to form planets. On Earth, complex amino acids formed by the aid of extreme heats, evincing the beginning of life, which proceeded to evolve. And the rest, they say, is history.
