I don't have a link to share, just seems to me that ancient man read the landscape and its spiritual and supernatural significance seems to pivot mostly around Dragon myths.
Tiamat is a Mesopotamian creator goddess who, along with her mate Apsu represent the waters and together give birth to the gods. After the gods murder Apsu to gain power, Tiamat (portrayed as a sea dragon) gives birth to the first dragons and makes war on the gods in revenge. When she is killed by Marduk (sometimes also described as a dragon or being served by dragons), the heaven and Earth are made from Tiamat's body.

It depends on what you mean by dragons, if you are thinking of the typical Tolkien giant lizard, fire breathing, winged fantasy animal it is going to be hard to find very early myths containing those, as these dragons are relatively modern (13th century).
If you instead allow for large mythological serpents with fantastical features then there are many myths.
In Mesopotamian mythology, Tiamat, as presented in the Enûma Elish is a large monstrous sea serpent that shaped the world (with the help of another god) and created the gods and monsters. Similarly, Gucumatz/Kukulkan/Quetzalcoatl in Mesoamerican mythology, is a feathered serpent that also brought forth the earth (with the help of another god) from the waters of creation. Australian Rainbow Snake is also a creator god. There is also the Greek Orphic alternative myths where a cosmic egg gives origin to the cosmos, usually hatched by a serpent.
Other honorable mentions of mythological snakes related to early myths of first gods include Egyptian Apophis (born from Ra), Greek Typhon (father of monsters) and Chinese Nüwa (creator of mankind).
