How did God come from?

Lz always asks that everything has its origin. Since God created everything, how did God come from? In fact, this problem illustrates the limitations and influence of our limited concept. If someone says that God was born by his mother or made by God, then the landlord can continue to ask, how did God's mother come or how did God's God come, how did God's mother come and how did God's God come? This cycle, because in our concept, but God says "I am me", I am myself, eternal.

God created the world. He is the Lord of all things. He created everything from nothing. Therefore, God is the first cause. As the first cause, it is impossible to produce it, because everything must be produced from the first cause, but the first cause itself cannot be produced from anything else. If the first cause is also produced, then it is not the first cause. Furthermore, because the first cause is not produced, it must be immortal, because if the first cause is destroyed, then if the first cause is assumed, nothing will be produced from it.
