That is really more of a geology question, but the answer is about 4.5 billion years. The sources are from the U.S. Geological Survey.

Scientifically the world is around 4.6 billion years old. We know this by looking at the composition of the sun, old rocks on earth, the moon and meteors. All formed around the same time out of the same nebula.

I have heard 4.5 to 5 billion years old. There are several substances used for radioactive dating, and they agree pretty well. Carbon-14 is used only for dating more recent items.
