I have always asked creationists this question:
You developed from a single cell into a fully functioning, multicellular human being in just 9 months. If this does not violate the 2nd Law of Thermodynamics, then how does the same thing occuring over a 3 billion year time period violate the same law?
To counter this argument, creationists have actually argued that the laws of thermodynamics can be violated within the womb. I kid you not. They also try to claim that if you have instructions on how to violate the laws of thermodynamics (i.e. DNA) then it can occur. I guess all we need are plans which say that a body of water at equilibrium can spontaneously produce boiling water and ice cubes at the drop of a hat.
