Uniformity of the Universe - Embarrassment for atheists

One of the remarkable features of the universe is that above a certain scale (about 10²⁴ metres) it is highly uniform in structure. This degree of uniformity is an embarrassment to cosmologists.
According to relativity theory, there should be no causal connection between points separated by distances greater than c multiplied by t (where c is the velocity of light and t is the age of the universe). Extrapolating this back to the Big Bang suggests that the primordial universe was partitioned into about 10⁸⁰ causally separate regions.
Nevertheless, all these disconnected regions had to expand at the same rate to maintain the observed degree of uniformity! Coincidence or co-operation?
Small wonder that Paul Davies (I hope the atheists know him) comments:“It is hard to resist the impression of something - some influence capable of transcending spacetime and the confinement of relativistic causality - possessing an overview of the entire cosmos at the instant of its creation, and manipulating all the causally disconnected parts to go bang with almost exactly the same vigour at the same time, and yet not so exactly co-ordinated as to preclude the small scale, slight irregularities that eventually formed the galaxies, and us.”
