And God said,
Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven.
All Commentaries on Genesis 1:20 Go To Genesis 1
Augustine of Hippo
AD 430
[The Manichaeans] usually find fault, questioning and often misrepresenting Scripture for saying that not merely those animals that live in the water but also those that fly in the air and all winged creatures were born from the waters. Let them know that learned men who carefully investigate these matters usually include with the water this cloudy and moist air in which the birds fly. For it comes together and becomes dense with the exhalations and what I might call vapors of the sea so that it can support the flight of birds. Thus on calm nights it produces dew, and drops of this dew are found on the grass in the morning. .
