Answer:
A report on ancient Greek gods and goddesses would be best described as a myth.
Explanation:
A myth is a narrative in its original meaning. In the religious myth, the existence of human beings is linked to the world of gods or spirits.
Myths claim validity for the truth they claim. Since the Greek Enlightenment, the pre-Socratics have criticized this claim to truth. For the Sophists, the myth is in contrast to the Logos, which tries to substantiate the truth of its claims by means of reasoned evidence.
In a broader sense, myth also refers to people, things or events of high symbolic importance or just a wrong idea or lie. For example, the adjective "mythical" in everyday language is often used as a synonym for "fairytale-vague, fabulous or legendary".
The ensemble of all myths of a people, a culture or a religion is called mythology.
As the report talks about the Greek gods and their different characteristics, it refers to myths about their existence.
