As Denise has mentioned, chimps are our closest living relatives but there were many intermediate forms between the common ancestor of humans and chimps. Why are you not considering these intermediate forms? Didn’t it take a long time (about 200,000 years) for humans to compose the music for an opera, sing Nessum Dorma, and produce a space shuttle? During that time, the human genome hasn’t changed much. In addition, many of us have 1 to 2% Neanderthal DNA mixed into our genome. Neanderthals are genetically more similar to Homo Sapiens than Chimps are. Let’s says that Neanderthals didn’t go extinct, do you think Neanderthals could have composed an opera at some point in the last 600,000 years? How about the Denosivans? Do you think if they survived to this day, they would have discovered the natural laws of science such as quantum mechanics, general relativity, and the genetic code?
My point is that it was humans who discovered the laws of nature over thousands of years. If Neanderthals lived to present times, they too would have discovered the exact same laws of nature that we discovered. But I am sure that Neanderthals would not have came up with the same story of creation as written in the bible. To me, this says the biblical story of creation can’t be deemed more credible than what we know is true about the nature of the universe.
