In religious Studies, the word myth means?
Something that cannot be proven
The second option. A myth is just an entertaining story that often makes moral point. A religious myth is historically untrue (or has a flimsy basis in history). It is a story that reveals truth but not facts. Nobody wrote what we think of as history back in biblical days.
A myth is the ancient people’s way of interpreting events that happened around them. It is the pre-philosophical mind’s interpretation of reality. The way to appreciate them is not to test them against the logic of present-day known scientific facts for they observe their own set of logic, and in most cases they are originally first-hand accounts of actual physical or historical events.
For instance, ancient people saw a solar eclipse. Since, obviously they do not know yet the celestial mechanics of one heavenly body casting its shadow on another, they might interpret it as a divine being covering the sun with its hand.
Rather than treat myths in a disparaging or patronizing way, we should realize myth-making is not a pre-occupation of the ancients. Peoples from every historical period made their own myths. In our own time these are either called conspiracy theories or alien sightings.
“A story that is psychologically meaningful and may be either historically true or not”
That’s closest to correct. More correct would be:
“A story that may be either historically true or not”
The Theory of Evolution.
The third answer is correct.
