Plants and animals evolved, but humans were directly created. All life was directly created by supernatural intervention. Evolution of a sort occurred, but it was guided by periodic intervention. Many more hybrid scenarios could be listed, but the main point is that while my bias precludes atheism, it still leaves me open to consider a wide variety of life-origin possibilities. Empirical Problems Before looking at the empirical problems with evolution, two observations should be noted about the nature of scientific theories and their empirical test.
All theories work on paper.
Any scientific theory can be described so that it sounds correct, even manifestly correct. The reason why an empirical test is needed is because on paper a theory can make any assumptions it needs to make in order to work. Often, these assumptions turn out to be false when the empirical situation is evaluated. Negative evidence is more important than positive evidence. Usually, this is why the theory was formulated in the first place.
