Easy answer: its too hot.

The deepest man made hole is Kola Superdeep Borehole. That was a Russian experiment to see how deep you could drill into earths crust, reaching down 12,262 meters. At that depth the temperature reached 180 °C. The scientists estimated that a 15,000 meters depth the temperature would reach 300 °C, and at that temperature the drill would cease to work and the project was stopped.

They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and  triggered the evolution of complex life.
