"The Law of Energy Conservation—`Energy can be converted from one form into another, but can neither be created no destroyed,'—is the most important and best-proved law in science.
"The First Law of Thermodynamics states that the total amount of energy in the universe, or in any isolated part of it, remains constant. It further states that although energy (or its mass equivalent) can change form, it is not now being created or destroyed. Countless experiments have verified this. A corollary of the First Law is that natural processes cannot create energy. Consequently, energy must have been created in the past by some agency or power outside and independent of the natural universe. Furthermore, if natural processes cannot produce the relatively simple inorganic portion of the universe, then it is even less likely that natural processes can explain the much more complex organic (living) portion of the universe."—Walter T. Brown, In the Beginning (1989), p. 12.
How does it work for evolution?
