Quantum uncertainty drives the early universe’s non-uniformity.

Evidence

The uncertainty principle implies that the early universe cannot have been completely uniform because there must have been some uncertainties or fluctuations in the positions and velocities of the particles. — Hawking, Stephen, A Brief History of Time, 247
