No because as you get deeper inside the earth the temperature gets more hotter (inner core). Also if you try to dig inside the earth it would be spinning constantly (1000 miles per hour)
The center of the earth is surrounded by molten rock known as magma. You would get around 5-25 miles down into the crust before you would be met with magma. There is 3700 miles of magma until you would reach the core.
