What is who created god?

It's important to acknowledge that the question "Who created God?" is based on a premise that God was created. This premise is not accepted within many theological frameworks, particularly those of monotheistic religions like Christianity, Islam, and Judaism. In these faiths, God is understood to be the uncaused cause, the ultimate source of existence, and therefore not subject to creation.

The concept of God having a creator typically arises within philosophical discussions or critiques of religious beliefs. If a being created God, then that being would seemingly become the "true" God, leading to an infinite regress problem. This is a common argument used by atheists and agnostics. Therefore, there is no agreed-upon answer to this question as its premise is often rejected.
