Q:To answer your earlier question, nothing outside of time and space created the universe. It is a nonsensical question. There was no time or space prior to the universe's inception (a statement that is flawed within itself as there was no such thing as "prior" to the universe, as time had not yet existed), nor is there any physical existence outside of time or space or any type of creator to reside in. Short answer: universe essentially created itself through gradual expansion.
How can something, that clearly had a beginning, brought itself into existing by… already existing (created itself through gradual expansion)?
