Detailed explanation-1: -There are several main pieces of evidence that support the Big Bang theory. One is the fact that the universe is expanding, proven with something called red-shift. The second is something called cosmic microwave background radiation. The third is the abundance of different elements in the universe.
Detailed explanation-2: -Evidence from red-shift This means that the further away the galaxies are, the faster they are moving. This is similar to an explosion, where the bits moving fastest travel furthest from the explosion. Red-shift data provides evidence that the Universe, including space itself, is expanding.
Detailed explanation-3: -It has passed through various stages, all of which can be considered cosmological theories. The flat Earth, the geocentric model, heliocentricity, galacticocentricity, the Big Bang, the Inflationary Big Bang… Each model explains what was known at the time and what the measurements could confirm.
