If all the quarks, gluons, electrons, photons, gravitons and so on in existence came from a single-point event, are they all quantum entangled? (Strange Universe Series)

We are closing in on where I’ve been going with this Strange Universe Series of questions now. In the question at the top of the list below, we established that when two particles become quantum entangled, measurements made to one in such a way as to collapse its quantum wave function instantaneously collapse the wave function of the other particle or particles that are entangled with it, and this is true even when the two entangled particles are located at distinctly remote points.

We established in the 2nd question near the bottom of this list that quantum entanglement can stretch over any distance from a few angstrom units to billions of light years, and will still act instantaneously.

These two facts leave me wondering how much in the Universe is already quantum entangled with many other particles. Wouldn’t the big bang have scrambled all their entanglement capacities? If so, would their entanglement persist right up until today?
