Why Shouldn't the Universe Exist?

The absence of a universe would imply the absence of all matter, energy, space, and time. There would be no concepts of existence, consciousness, or meaning. The question "Why shouldn't the universe exist?" is inherently paradoxical as it presupposes the existence of a universe in order to contemplate its nonexistence, inviting further philosophical inquiry into the nature of existence, nothingness, and the boundaries of human understanding.
