How did carbon, nitrogen and oxygen get in the universe? Abundant potential energy densely existent motionless without time, becoming potential energy in the form of stable matter and various types of non-matter radiation and waveforms. The universe at its most basic, fundamental level is all energy, colliding and interacting with other energies. Some theoretical physicists argue that energy in itself is a flawed concept, and the universe is nothing but a singular present event with many different aspects, thus nothing is a 'thing', but a 'happening'. This is getting into the theory that time is not an affliction but an intrinsic property of 'stuff'.
The nature of the universe isn't temporal as you envisage temporality. It is not deterministic, it is relative.
