We can all conceive of a state of affairs (a possible world) where nothing at all exists and another state of affairs where they do.
And yet I can conceive of God not existing in one possible world yet existing in another. So that's not how you argue against metaphysical necessity of an entity.
Suppose the cosmos is all that there can possibly be, with all possibilities actualized (via multiple universes and multiverses), then going with modal logic, there is no possible world where such a cosmos is not a thing.
Enough special pleading.
