Actually, it's the other way around even though it's very similar! Apophis is generations older than Horus, as he belongs in the same generation of Ra. Whereas Horus was the deity of the skies, Apophis is mostly believed to have existed in the underworld even after Ra fought him successfully. Zeus is younger than Cronus. xD

Ack got those mixed up, Cronus carrying around Zeus' lightning bolt.

Also wasn't Horus some form of war god? He was two generations down from the Goddess that embodied the sky. 

Nut -> Osiris and Isis -> Horus

Though the Egyptian divine genealogies were super fucked up.
