Which theory posits that a water vapor canopy existed around the earth before the flood?

The theory that posits a water vapor canopy existed around the Earth before the flood is known as the Canopy Theory. This concept suggests that a layer of water vapor surrounded the planet, acting as a protective shield from harmful radiation and contributing to a stable, warm climate. Proponents of this theory argue that this canopy could have resulted in conditions that allowed for the flourishing of life as described in early biblical accounts, including the narrative of the flood.

In contrast, the Day-age theory interprets the days of creation in Genesis as long geological periods, which does not specifically address a canopy of water vapor. The Gap theory suggests there is a time gap between the creation of the Earth and the events described in Genesis, focusing on chaos before divine order, rather than a canopy as a significant feature before the flood. Progressive creationism views the creation process as ongoing and involving evolutionary mechanisms, which again does not support the specific notion of a vapor canopy.

The Canopy Theory provides a unique perspective on pre-flood conditions, emphasizing the role of the atmospheric structure in the environment of early Earth.
