I didn't miss that. Neither did scientists.
And you're wrong anyway. What it would mean, with an initial, homogeneous state and no quantum fluctuations, is that there would not even be galaxies. That the universe would.just be a sooth, homogeneous mix of hydrogen and a little helium. Not that the galaxies would be "evenly spaced".
But the above conditions didn't happen in this universe. In this universe, we have fluctuations at the quantum level. These fluctuations created the seeds that formed objects that attracted other objects via gravity.
