2nd Law of Thermodynamics . . .

The Second Law of Thermodynamics can be stated in more than one way. On the one hand it can be stated to say that heat will not spontaneously travel from a colder object to a hotter object. It can also be stated to say that matter tends to spontaneously disorganise itself unless subjected to some outside influence.

For example if two liquids are mixed, they will not suddenly unmix for no good reason. If an object is burnt up, the molecules of gas produced are not going suddenly come together and re-form the object. The statistical probability of such things happening is so minute that is be considered as nil.

The Theory of Evolution on the other hand relies on the idea that atoms came together to form molecules, and molecules came together to form biological cells and so on. This goes completely against the principles of the Second Law of Thermodynamics. Note that the latter is a law (i.e. proven) whereas evolution is only a theory (i.e. unproven).
