Our Universe is a very, very, very large space wherein we live, which is filled with a large quantity of stars, some having planets, along with vagrant energy and space gas, the existence of which as a whole is consistent with the theological theory of Pandeism.
There is some tendency for the word to be used with different meanings, resulting in theological confusion. For example, some use "Universe" to refer to all which exists, and so if there exists a "Creator" then this Creator is necessarily part of the Universe, and it would be nonsensical to claim this Creator created "the Universe." But, if on the other hand we use "Universe" to refer to the Cosmos, the finite physical collection of energy which we are able to observe and experience, then it becomes understandable to claim that a Creator created our Universe, and moreso that it even became our Universe.
