"superhuman being or spirit worshipped as having power over nature or human fortunes"
Word god is very interesting because it is really an ancient one, but naming this entity depends mostly on the religion so thats why you would find fewer similarities throughout the world. Some of the tribes did not even have a word such as "God" untill europeans colonised their lands and teached them about christianity so a lots of them took the english word and called this worshipped entity just god.
Advice: Try to focus on the ancient languages this time
