ICly, everyone knows about Carteneau since it happened only 5-6 years ago. Not everyone might be able to tell it was the Elder Primal Bahamut that came out of Meteor but I don't see it as a rather hard feat considering many have probably directly witnessed it all the same anyway.
So, any character that is basically... older than 5 has basically lived through the rampage caused by Bahamut, directly or indirectly. It means that they might have seen him raining death all around in the skies above Carteneau if they were at the battle (and the regions around, considering its size), or they might just have seen death raining from the various chunks of Dalamud falling all around when the moon opened. The biggest of those crashed at various places, as can be seen in Thanalan (the Burning Wall), Limsa Castrum Marineris, or in the North Shroud, or various other places.
You basically would have to have lived in a very far away land at the other side of the planet not to have lived through that hell.
Now then, as Louisoix casted his final spell that propelled the warriors of light into the future, it also seems to have affected the minds of everyone and they have a hard time remembering anything about those heroes (but the Scions for example eventually do when they meet them in the flesh 5 years later, for those who played through 1.0).
So, in a nutshell, everyone can remember the Calamity and the (short lived) Umbral era that followed. Everyone however pretty much forgot about the Warriors of Light of the Sixth Astral Era (1.0). They however, know about the WoL of the Seventh Umbral and Astral Eras (2.0 and 3.0).
