God has left effects behind that allow us to reason back that He exists, because He is the cause of these effects. The cosmic microwave background radiation provides evidence that our universe had a beginning. God is the best explanation of the way things really are regarding these matters ~ the best explanation of reality regarding these matters. And one of the ways things really are regarding these matters is that the universe was created out of nothing.
There was no space, time, or matter ~ but the entire universe came into existence. And if that’s so, the cause can’t be made of space, time, or matter because space, time, and matter were created. So the cause must be spaceless, timeless, immaterial ~ and personal.
Personal because to choose to create something is necessary to go from nothingness to a state of creation. And only persons can make choices. Impersonal forces don’t make choices. Gravity (for example) doesn’t decide to do things; gravity just does what it does over and over and over again. An impersonal force does not have the ability to make decisions. This is an attribute of persons, not impersonal forces.
Regardless of how old it all is, God created the universe.
