Who create God? Why there is always a confusion, misunderstanding and debates on the topic of God? Why do people want God? Isn't we are the one to make everything possible? We don't have to give our faith and hope to God. Isn't it ? Why God exists in all people mind? 
God exist eternally, And no one knows what God's in mind but He knew the mind of all people in the world, together with all the creatures from the sea, land, underground, neither creatures in the sky or all kinds of plants He knew it too. Which shows that God is really powerful.God is strong, but he created and did not explain to people the whole essence of the universe because of which chaos constantly arises.
In this case, with the opposition of people, it can be seen that the creator can not control his creations. There are disputes and wars that lead to numerous victims. He did not think well of the creation of mankind.
Of course that Creator can control His creation but He don't want it.
He gave us ''free will' in order that we can qualify to become ''co creators'' and God's children.
God didn't want to create ''robots'' without free will but independent beings which can learn and grow every day and ultimately reach high spiritual standard, and unite with God.
Jesus: ''Be perfect as your father'' and ''don't you know that your body is Gods' temple''.
Of course, before humankind reach perfection, we will see a lot sins, conflicts and problems but there is no other way how human beings can achieve perfection.
After all, our lives on the earth are very short compared with eternity in spiritual world.
