Question

How old is God?

Answer 1

God is definitely more older than the universe for sure. Also God is not affected by time, space or matter, thus making your question not a sensable one at all. However, your question is respected in all ways.

Answer 2

as old as time itself

Answer 3

As a divine being, God is often considered eternal and timeless, existing outside the confines of time as humans understand it. Therefore, the concept of age may not apply to God in the same way it does to humans.
