It was then that gravity was created.

The Universe cooled enough to allow for the formation of atoms, the building blocks of everything more complex in the Universe.

Energy could no longer be created or destroyed at the end of the plasma Universe.

At the end of the plasma Universe, 380, 000 years after the Big Bang, human existence began.

Detailed explanation-1: -Why is the end of the plasma Universe so important to the creation of greater complexity? Energy could no longer be created or destroyed at the end of the plasma Universe. At the end of the plasma Universe, 380, 000 years after the Big Bang, human existence began. It was then that gravity was created.
Detailed explanation-2: -As the universe continued to expand and cool, things began to happen more slowly. It took 380, 000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe.
Detailed explanation-3: -A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.
Detailed explanation-4: -The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansion-and cooling-of space itself.
