The Sanskrit word is “deva”. This comes from the same Indo-European language root as the Latin “deus”. They are non-material living beings.
Here is one of the Buddhist devas describing himself:
“I am the Brahma, the great Brahma, the conqueror, the unconquered, the all-seeing, the subjector of all to his wishes, the omnipotent, the maker, the creator, the supreme, the controller, the one confirmed in the practice of jhana, and father to all that have been and shall be. I have created these other beings.”
– Brahmajala sutta, Digha Nikaya 1.
Does that god sound familiar to you? I have added some emphases to assist.
The gods who are not enlightened are not as good a source of advice as the Buddha. The gods who are enlightened are themselves Buddhas and offer exactly the same advice.
