If the universe is eternal, then there is no necessity for an ultimate mover or a creator demiurge because everything in the universe has always existed and is transforming and moving in accordance with the laws of physics. But the universe cannot be eternal because it does not contain any component that does not undergo transformation. From common sense experience we know that all things which undergo transformation are either material or mental—they have a beginning and an end. If everything in the universe is undergoing transformation, then eternality cannot be attributed to the universe as a whole. The universe must have a beginning. If it has a beginning, then it implies that there is a creator.
