Bull puckey. A dozen lines of independently-verifiable dating methods have narrowed the range down to about 4.5 billion years.
Do yourself a favor, read Radiometric Dating: A Christian Perspective. You'd be surprised at just how much science does know.
How does bull puckey taste??? How did it evolve??? Enquiring minds want to know.
Actually, I wouldn't know for sure if they were verifiable. I wasn't alive when the original material was around. Hmmmm..... "narrowed it down..." I have narrowed down the place where I left something down to a few patches of the lawn, but I still don't know EXACTLY where it is. NO ONE KNOWS FOR SURE EXACTLY.
And no, I'm not one of those who regards all science as bull pucky because it doesn't favor creationism. People forget that without science, all of our technology advances would not be possible today.
