If everything exist at the same time and nothing should exist in the first place then then, everything is as real as it is an illusion. Infinity is both infinite and infinitesimal. Past, present, future it’s all the same. There are no distinction. The passage of time is only responsible for reflecting the nature of reality itself. To take things from existence to non-existence and then to another state of existence. There is nothing else but paradox, we are a result of a paradox, we only exist because of a paradox of cosmic scale.
