Science says the universe is 13.8 billion years old, the Solar System is 4.6 billion years old, and the Earth is 4.5+ billion years old. In short, secular science would conclude Adam was age 30, the Solar System is 4.6 billion years old, and the Earth 4.5+ billion years old because it looks that old even though it is not. When a scientist estimates the Earth is 4.5+ billion years old, he is assumed to be correct because, from the evidence, it appears to be 4.5 billion years old, just as, from the evidence, Adam appears to be 30 years old even though, when created, he was only a few seconds old.
