origin of GOD?

God is not in the category of things that are created, or come into existence, or are caused. God is uncaused and uncreated. He simply exists. He is ever existing and hence His origin need not be questioned. From nothing, nothing comes. And hence if there was ever a time when there was absolutely nothing in existence then nothing would have ever come to exist. But things do exist. Therefore, since there could never have been absolutely nothing, something had to have always been existing. That ever-existing thing is what we call God.

What you say is true. He is not a created being. Psalms 90:2 Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.

The answer to your question lies in what you visualise and how you think of the word God.

i don't believe that God has the beginning, you can't find any record of His Origin. You can only find how he create the universe and human. God is superior, no man can explain on His existence as a spirit being. He has the power that no can even see Him in person. Only we know that He exist and He also said in the Bible about His attitude and how He manage human in the time of Israelite.
