Hey... what’s race got to do with it?
Sorry...just kidding, check this out though.......

What method's used to date the zircon?
From Wikipeadia: Uranium-lead dating is usually performed on the mineral "zircon" (ZrSiO4), though it can be used on other materials. Zircon incorporates uranium atoms into its crystalline structure as substitutes for zirconium, but strongly rejects lead. It has a very high blocking temperature, is resistant to mechanical weathering and is very chemically inert.
This is my bet. But there might be other data. Was it incorporated in sediment, which if precambrian, by cross-cutting relationships would make it older, and the diamonds in it even older....
Gee, I love that kind'a talk.
All to God.
Soooooo, the chicks have been waitin' fer da prize since the gitgo?
Thats gotta mean they travelled back in time.......
See americanantigravity.com for the true story of how the earth-moon system formed.
OMG! I can’t believe I wasted some much time is school when I could have just been watching James Bond movies all along. Dang! The waisted years!
Thermodynamically, diamonds are metastable. Graphite is the lowest energy state of carbon.
The zircon crystals come from the dawn of geological time. Later meteorite bombardment destroyed much of the early crustal rock and much of the remaining crust has been destroyed by weathering and erosion or recycled deep into the interior through plate tectonics.Thanks DaveLR for the bling bling ping, and Blam for the topic. This problem has many facets.

They left out the part that there was a footprint on it that looked like Helen Thomas’s.
