How was the universe created?

Answer 1

By the Big Bang

Before the Universe came into being, the Universe was a singularity (undefinable). At Planck Time (#10^-43#) seconds, there was a perturbation in the quantum foam. As a result of this excitation, symmetries were unlocked, there was rapid inflation, and the Universe came into being.
