What does cosmogeny mean?
Cosmogeny refers to the origin and development of the universe as a whole, and by extension to any systematic account or theory that explains how the cosmos came into being. The term belongs to formal registers, appearing most often in astronomy, cosmology, philosophy, and the comparative study of religion, where scholars contrast scientific models of cosmic origins — such as the Big Bang theory — with the creation narratives of ancient and traditional cultures. A related and more frequently used spelling is "cosmogony," which carries precisely the same meaning; readers should treat the two as interchangeable variants of one word rather than distinct terms. Derived ultimately from Greek roots meaning "world" (kosmos) and "birth" or "coming into being" (genesis), the word literally suggests "the birth of the universe." Cosmogeny is useful whenever a writer wishes to speak broadly about theories of cosmic beginnings without committing to any single account, whether empirical or mythological.
The origin and evolutionary development of the universe; the field of inquiry concerned with explaining how the cosmos came into existence.
"Debates over cosmogeny once belonged to philosophers and theologians before becoming questions for physicists."
A specific account, model, or narrative — scientific or mythological — describing the birth of the universe.
"Each ancient civilization preserved its own cosmogeny in sacred texts and oral tradition."
The plural is regular and typically appears when comparing multiple cultural or theoretical accounts of the universe's origin.
"The lecture compared the cosmogenies of several ancient Near Eastern cultures."
Before telescopes and physics, every civilization answered 'where did everything come from?' with its own cosmogeny — and we still tell those stories today.

Etymology of cosmogeny
Cosmogeny derives from Greek elements: "kosmos" (order, world, universe) combined with "genesis" (origin, birth, coming into being). It entered English in the early modern period through scholarly Latinized formations, sharing its roots with cognates such as cosmology, cosmography, and cosmic. In contemporary English it functions chiefly as a learned variant of the more common "cosmogony," and both spellings trace back to the same Greek source material.
How cosmogeny is actually used
A formal, scholarly word found mainly in academic writing on astronomy, philosophy of science, and comparative religion. The spelling "cosmogony" is considerably more common in modern usage; "cosmogeny" appears as a recognized variant. The adjective form is usually given as "cosmogonic" rather than from this spelling.
