A Short History of the Early UniverseThe Big Bang started the chain of events that eventually led to the Earth and mankind. After the initial "Bang", the Universe expanded like a giant balloon. While this expansion was taking place, the initial "dust" (hydrogen,helium) formed into "structures" where gravity started pulling them together.
First, Hypergiant stars (the size of galaxies) formed, and they "burned out" quickly - supernova-ing and "enriching" the surrounding dust with heavier elements (metals), while becoming supermassive black holes.
