Incorrect, Taz. We have ample evidence for how the universe began. We know exactly what created the massive background radiation that we can observe. Paired production annihilation from a runaway quantum fluctuation false vacuum. There were 1 billion paired particles (anti-matter/matter pairs) for every one particle of remaining matter. The paired particle annihilation released tremendous amounts of energy which propelled the remaining matter particles outward and powered the expansion of the universe. So there is literally only one way the background radiation can exist... the creation of the universe from nothing.We don't know. Suggesting otherwise makes that person a fool.
