Not all religions point to the same god
According to most religions God is independent of this universe (he existed before the universe and he created the universe).

So most religions would probably say that God is not an ET.
The Abrahamic religions all accept the concept of one God. These do vary in names. All of these religions also recognise a Kingdom of God, or a place where God is the King. The Quran does not mention the Kingdom of God but does mention Abraham seeking the kingdom of the Heavens.
Not all religions recognize a deity, like Hinduism in which there is no deity.
Various religions, such as Christianity, Islam, and Sikhism, have teachings that emphasize the equality of all individuals before God. These religions advocate for treating others with respect, compassion, and equality, regardless of their social status, ethnicity, or background.
All religions believe in a god. However if you are speaking of the Christian God, then the answer is the Jewish, Christian, and Islamic people believe in God.
