Christians believe he is really present, in this universe and in you. It is in The Bible in John 1:1. You live in this earth and all the universe in the beginning was the Word/(spirit). He especially died on the cross and wanted to tell you that God really is present. As soon as you repent and accept the Holy Spirit and deny the flesh ....that is the God present. Knowing God is present can come from reading about Jesus Christ from the Gospels, especially from John and learn only words that come from Jesus.
Opinion:No, he is not present.You really get an answer from the Almighty, there is only one God, one creator
Some do and some don't.
God is the Universe. The Universe is God.
because it explains the origin of Universe and what it really made of.
Atenra was the Egyptian god of the universe.
God created the universe by order.
As nothing is impossible God, and that God is bigger than the universe, I doubt God would have any trouble managing the universe.
yes, God is the master of the universe because it created the universe and it will one day destroy the universe.
This is really an opinion. Some believe that god created the universe, and some believe that it was the big bang theory. I myself, being an athiest, believe that it was the big bang, but i really have no idea.
Has God created the universe.
Does God really need a reason to do anything?
Well unless you think the universe always was and always will be then I'd say that he made the universe. If he specifically made humans, I don't know.
