According to the big bang theory, which describes the universe before the actual big bang occurred?

the answer is hot,dense points; each smaller than an atom

Explanation:

the big bang theory was proposed to suggest the expansion of the universe by describing the origin of all components of the universe and its planetary bodies. its suggested that the whole universe was in a state of high temperature and highly dense points (which were smaller than atoms) but continuously expanded by cooling down which gave rise to the formation of subatomic particles, atoms, etc.
