Fantastic find! As you well know, there are three types of rock. Igneous, Metamorphic, and Sedimentary. Sedimentary rocks form from pieces of Igneous and Metamorphic rock that have been shucked off by erosion, but they can also form from the hard parts of animals, mostly composed of calcium. A great example of this is Limestone, where we can find the shells of animals that have been extinct for millions of years!
So while sedimentary rock can form in a very short period of time, the parts that make up the sedimentary rock can be very old. In fact the oldest metamorphic rock can be found in the Nuvvuagittuq greenstone belt in Northern Quebec, dated to over four billion years!

The age of rocks is not determined by looking at them, it’s determined by using measurements such as uranium, strontium, and/or rubidium decay. This article displays your basic ignorance of what you are arguing against and ultimately seriously undermines your position. No scientists claim that all rocks are millions of years old.

Forgive me if I’m bursting your bubble, but just because a rock has elements of a toy car on the underside does not mean the rock could only have been created in the past 10 to 20 years. The rock itself is still quite old, probably millions of years. The fact that there’s a toy car on the bottom indicates to somebody whetted away at the rock and used it to make a more modern toy. The fallacy lies in the that the rock was not created along wit the toy, as one could mistakenly be led to believe through your article. the rock is not young due to the toy car no more than a mountain is young because we have tunneled a hole through it.

There is a difference between fossilization and concretion.

This is not even wrong. Put another way, your article did not even achieve the relevance to be considered wrong. Put still another, it would be unclear without context whether or not you were making an ironic joke. The people you speak for should be insulted.

I put this example to an evolutionist and he said it was due to concretion and that was not fossilization. Can someone clarify. Thanks. Tas Walker responds:
Google will help you. The point is that old-looking rocks can form quickly, contrary to the general perception in our culture.
