The earth is not 6.4 billion years old. It’s 4.5 billion years old. Anyway, you’re just using the god of the gaps approach... just because you don’t understand or believe what the evidence points towards does not mean that it was intelligently designed. Other than the fact that almost all fields of science completely contradict the biblical account of creation, I don’t see what’s so difficult to understand about evolution? Nothing in the universe remains stagnant and unchanging.
