You might've shown how you used the Bible to measure that 4.5 billion years. Since the King James Bible is a translation, even if by some hocus-pocus you can show that, that is subject to interpretation. Is there some spiritual component to life? Perhaps. Perhaps such serendipitous events are occurrences that we simply don't have the answer to explain, yet. I think it's more likely that the earth has been visited by more advanced life forms than that "God" exists.
