The terms "origin science" and "operation science" are used to explain the nature of science, especially as it relates to history. But they are an inadequate response to positivism. The proposal for multiple kinds of science was an attempt to answer claims from the 1980s creation trials that evolution was science and creation was religion. Proponents of "origin" and "operation" science sought an alternative inside science, rather than in the broader context of the Christian worldview. In addition to problems in their view of the history of science, "origin science" fails its own criteria and "operation science" is redundant. The past and singularities, key factors in this scheme, are not proper topics of science. Finally, the proposal includes a deficient understanding of uniformity and mistakenly accepts the "god-of-the-gaps" fallacy and methodological naturalism.
