The whole things seems like such a massive living system that I cannot help guessing that what we think of as universe is just a somewhat large single creature.

It's an appealing idea, but surely there'd be insurmountable problems with the distance/time involved for any part to communicate to another part? It'd be like trying to run a computer with a clock that takes millions (billions?) of years to make a single tick. I just don't see that it's at all feasible and that's without even trying to guess as to how different parts can change behaviour depending on its environment (one commonly used requirement of "life").

Much worse than that, the universe is enormous and it is expanding faster than the maximum possible velocity, as a result such a clock could never complete a single tick.
