Figures in Australian Aboriginal mythology known as the Dreamtime could count. Their mythology and culture is thought to be between 40-60,000 years old, though because there were over 500 nations beliefs did differ. Though the most prominent figure in most of their mythology is the Rainbow Serpent which is most commonly seen as a creator god which started the dreamtime. And of course we know heaps about their follows as obviously Aboriginal Australians still exist today.

Comment: do the reconstructed Proto-Indo-European deities count? e.g. Roman "Jupiter", Greek "Zeus", Sanskrit "Dyaus Pita" from PIE *Dyēus Ph₂tēr ("Sky Father").
