Hypothetical: If the human “experiment” fails and we destroy ourselves, what happens to the expression of consciousness at this level of intelligence?

Kind of a hypothetical scenario, but let’s say we destroy ourselves via thermonuclear warfare and the human species is wiped out, what happens to the expression of this level of conscious intelligence?

Is it just wiped out for good until another several billion years when the circumstances are ripened again for it to manifest?

We know the planet 🌎 will still go on and find ways to maintain equilibrium. Amoebas, bacteria, plant life and sea life may survive.

Will we just be in a void for another several eons before we can come back in physical form?
