God may be or may mean several different things to each individual. There are many religions and beliefs and so having an exact answer to this question is simply impossible. Many people believe in God and in Jesus, others simply believe in animals and other gods...some people do not believe in anything at all. My point of view is that God, Jesus and so on they are good energy that pour blessings in our lives. It is hard to live a life and not believe in anything, and even though the Bible might not be 100% accurate (as we were not there to see things happen with our own eyes) it gives people guidance so they see meaning in life and do not feel like they were born out of randomness.
