Those who want evolution taught without the clear evidence opposing it, in effect, wish to censor a large body of scientific evidence from schools. That is wrong. Also, the consequences of a global flood have been misinterpreted as evidence for evolution, not as evidence for a flood. That misinterpretation, unfortunately, is taught as science.
Broad, but increasingly precise, relationships are sought between causes and effects. These relationships, called scientific laws, help predict future phenomena and explain past events.
Notice, this does not mean the first cause must be naturalistic. It is poor logic to say that because science deals with natural, cause-and-effect relationships, the first cause must be a natural event. Furthermore, if the first cause were a natural consequence of something else, it would not be the first cause.
