Initially what was to become the Universe was a particle of very high energy, or in other words a particle with a very high energy state. Some unknown event caused this particle to decay into a lower energy state during which various forms of matter, energies, and fields were produced. At first the decay was very rapid and resulted in inflation, as well as fields which we call space and time. This decay continues today, but is much more gradual and we observe this as dark energy expansion of space and time. Is this creation description useful?
