Many scientists committed to naturalism claim life’s rapid emergence on Earth establishes that life must be common in the universe. However, an Australian physicist, arguing from a naturalist perspective, asserts that life’s rapid appearance on Earth does not prove that life is common in the universe. At least ten complex steps exist between Earth’s first life form and humans, and only 3.8 billion years separates the first life form from humans. Therefore, all the steps, including life’s origin, must take place rapidly on Earth regardless of the natural probabilities involved. Thus, it is unlikely that all these steps have been duplicated elsewhere in the relatively short time period the universe allows.
