Intelligent Design
Tantamount to "God of the Gaps": a theological concept that emerged in the 19th century and revolves around the idea that gaps in scientific understanding are regarded as indications of the existence of God.
Well known historical candidates: Newton - aspects of the solar system, the complexity of the eye.
These days the main candidates are complex molecular machines and the values of the fundamental constants. The history of science tells us that, in time, these 'gaps' will be filled. Notwithstanding, the God of the Gaps argument continues to thrive, as George Santayana put it, "Those who cannot remember the past are condemned to repeat it."

And a very clear definition:  Scientific Theory

An interlocking and consistent system of empirical observations and testable hypotheses that has never failed scrutiny.
And a homage to science from Bertrand Russell
It is science that has destroyed the belief in witchcraft, magic and sorcery. It is science that has made the old creeds and the old superstitions impossible for intelligent men to accept. It is science that has made it laughable to suppose the earth the center of the universe and man the supreme purpose of the creation. It is science that is showing the falsehood of the old dualisms of soul and body, mind and matter, which have their origin in religion. It is science that is beginning to make us understand ourselves, and to enable us, up to a point, to see ourselves from without as curious mechanisms. It is science that has taught us the way to substitute tentative truth for cocksure error.

Bertrand Russell, The Art of Philosophizing (1968), Essay One, The Art of Rational Conjecture (1942), p. 11
