The anthropic principle, first stated by Brandon Carter, an astrophysicist and cosmologist from Cambridge University, states the universe we live in is a result of an interaction of factors, which, if randomly occurred, would make the resultant, our universe, extremly unlikely. Because of Carter's thoughts, theologists find evidence on the existence of a God who created us and the universe by refusing to believe the events leading up to the creation of our universe could be completely random. The anthropic principle does not support a personal, all good God, but does support the existence of something that helped make the chance of life existing on Earth and gives a logical explanation for why we are alive, but there is always the chance that life formed on Earth simply by random, but many shy away from this view because they don't want to believe that human existance is useless, I am not sure if human existence is useless, as a species, we have hurt the world around us, but we have also attempted to give back. The assignment is to explain the anthropic principle, not question its validadity, so...
To conclude, the anthropic principle claims that, because the chance of Earth being exactly where it is to the point support life is extremly low, if by random, and no other planet has been discovered that can also support life, God must have made it possible for our planet to be antiquate for life because Earth should not be above the statistic.
