At the absolute beginning of the universe, the conventional structure of causality breaks down.

As we trace the universe backward to its absolute origin, our smooth map of spacetime dissolves. In this extreme state, gravity and quantum forces collide, creating what physicists call spacetime foam. Here, time ceases to flow in a straight line. Closed loops form where the future of an event can actually be its own past. Because cause and effect loop back on themselves, the very concept of a 'trigger' loses all meaning.
