Mr Gordon,

Although up to now science has only managed to give tentative answers to the mystery of the origin of life that does not entitle you to say that therefore "the God of the gaps" must exist. The existence of atoms was first postulated in Antiquity but it took several thousand years for mankind to prove it.

Origins of the term

"From the 1880s, Friedrich Nietzsche's Thus Spoke Zarathustra, Part Two, "On Priests", said "... into every gap they put their delusion, their stopgap, which they called God.".The concept, although not the exact wording, goes back to Henry Drummond, a 19th-century evangelist lecturer, from his Lowell Lectures on The Ascent of Man. He chastises those Christians who point to the things that science cannot yet explain—"gaps which they will fill up with God"—and urges them to embrace all nature as God's, as the work of "an immanent God, which is the God of Evolution, is infinitely grander than the occasional wonder-worker, who is the God of an old theology...

In his 1955 book Science and Christian Belief Charles Alfred Coulson (1910−1974) wrote:There is no 'God of the gaps' to take over at those strategic places where science fails; and the reason is that gaps of this sort have the unpreventable habit of shrinking.andEither God is in the whole of Nature, with no gaps, or He's not there at all."
