Physicists at Washington University in St. Louis have found more evidence for the design of Earth for life. They discovered a uranium isotope that two billion years ago was responsible for life-limiting, natural, on-and-off nuclear chain reactions. However, the uranium isotope responsible for the chain reaction, U-235, has a half-life of 704 million years. Thus, natural chain reactions would be a problem for life only when Earth is less than 2.8 billion years old. Knowing this, the Creator could limit Earth life between 3.8 and 1.8 billion years ago to relatively radiation-resistant life forms like bacteria. Also, knowing how important an extremely high uranium abundance is for sustaining plate tectonics and a long-lasting internal dynamo, the Creator would create Earth at the peak uranium abundance epoch in cosmic history and ensure that Earth would receive an extra uranium abundance boost from the Moon-forming collision event. The fact that Earth exhibits such characteristics suggests advanced planning on the part of a supernatural Creator.
