If you knew the positions and velocities of each of the particles you'd have a definition of one single microstate. But there are lots of other microstates that would also be states of equilibrium. Now, look at a nonequilibrium state and you find that there are again, lots of different microstates that can form that nonequilibrium state. It turns out, though, that there are more microstates for the equilibrium state than there are for the nonequilibrium state, thus the equilibrium state is more likely, usually far more likely. That is the reason things tend towards equilibrium.To my mind, if we come to know everything about all the particles at equilibrium (just suppose), we wouldn't call it disorder AT ALL. Then the entropy at equilibrium would be zero.
The same scientific methods that produced the 2nd Law also produced the theory of evolution. So when you argue that one of those ideas is false because the other one is true you accept the validity of one of them based on science but you reject the the validity of the other, and you also base that on science! Thus you are saying that science is wrong because science is right.
