I brought myself to believe certain religious/mythic stories of a certain impact had always a basic truth behind, aside from the forgery. The universal flood? Probably a devastant flood in Mesopotamia eons ago. The exodus? We tend to forget in Egypt there wasn't proper slavery, the Hebrews were probably war prisoners then freed, becoming part of the Egyptian community and then for certain reasons went away. Maybe because of ties with the Atonian heresy?
Same for the Aeneid and the Iliad. That Troy existed is inoppugnable truth; that was rich proved the treasure found here even if it wasn't the one of Priamus; so one of the main sites found was burned to ground. Also, as the Greeks settled around all the Mediterranean, it could be possible some Trojan refugees settled in Latium, surely more safe than the Aegean or Magna Graecia.
