The same way all ancient people used it: they made up fanciful stories about giant birds eating the sun to explain sunset and gods having chariot races to explain thunder.
EDIT:
The ancient Egyptians used religion to understand nature with their gods. For example: Anubis was the jackal the Egyptians thought that the jackal was an animal that controlled death(as the Anubis mask was worn in mummification), and made it the god of death.
EDIT2: Above that ancient egyptians related volcanoes , earthquakes and other natural disasters to religious figures as a rage of one of their religious gods.
