The first and second laws of thermodynamics.
Not sure what that has to do with the age of the earth.
The fact that carbon-14 should break down to virtually nothing past a certain point in terms of dates and yet it is difficult to find carbon without carbon-14, which with an old earth model should be virtually non-existent much of the time.
dahs already covered this. Carbon 14 is produced in the atmosphere. Not sure why you would think it would be non-existent.
The fossil record shows many strata of rock which are thought to be formed over "millions of years" can actually form quite quickly. Sometimes there are fossils, including petrified trees, which span straight through several layers indicating they may have formed quite suddenly.
Can you explain this further?
