Question

How does the first particle /electron /proton came to exist in this universe before the formation of big bang

Answer 1

Answer:

According to the big bang theory, all the matter in the universe erupted from a singularity.

As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.

A few millionths of a second later, quarks aggregated to produce protons and neutrons.

Within minutes, these protons and neutrons combined into nuclei.
