Oldest Rocks Known Discovered
In a bit of news sure to leave creationists scratching their heads scientists have discovered what may be the oldest rocks on earth. As reported in Science and distilled into laymens terms in the NY Times, Richard W. Carlson and his colleagues have found bedrock which dates to 4.28 billion years old. If the discovery holds up, these rocks would be about 250 million years older than the previous find, in northwestern Canada. What is really significant about these rocks is not necessarily their age, but the fact that they indicate the earth had pretty much taken its present day form even way back then. The commonly held view is that at that time, the earth was a mess of molten lava. But this discovery puts that view in doubt, the form of the rocks indicates that the earth was pretty much like it is today, even 4.28 billion years ago. Regardless of whether that holds up, I find it amazing some idiots hold to the view the earth is just 6,000 years old.
