The question of whether the theory that God created time and space is valid is a matter of personal belief, philosophy, and religious interpretation. It falls into the realm of metaphysics and theology, which are subjects of diverse perspectives and interpretations.
Different religious and philosophical traditions offer varying explanations and beliefs regarding the origins of time and space. Some religious beliefs assert that a divine being, such as God, is responsible for creating the universe, including time and space. Others may have different explanations or views on this topic.
It's important to note that scientific theories, such as the Big Bang theory, provide scientific explanations for the origins and development of the universe, including the concept of spacetime. These theories are based on empirical evidence, observations, and mathematical models, and they do not necessarily invoke the concept of a divine creator.
Ultimately, whether one considers the theory that God created time and space as valid is a deeply personal and subjective matter that varies among individuals based on their beliefs, religious or philosophical perspectives, and their understanding of the available evidence.
