I'll only touch on a couple things here in there because I'm not good at keeping sourcable lore snippets around. (*lights the Sounsyy signal for that*)
The Calamity happened 5 years prior to the beginning of FFXIV A Realm Reborn, which is the 5th year of the 7th Umbral Era. It took place at the end of FFXIV 1.0 (the failed MMO), which would have been.....1572 of the Sixth astral Era.
At the time, we get the 2.0 Opening video. The less moon Dalamud was split open and out came Bahamut. Severe damage to the land occurred both physically and aetherically. Part of that damage that we can see in game now are all those crystals, which is effectively dead, crystallized aether. (Yet it still has energy. I don't really know how that works.)
But this is where it gets tricky. 1.0 players could have fought i nthe Battle of Carteneau, which led up to the Calamity. But nobody remembers them. Instead, the commonfolk remember a band of adventurers, shrouded in light. (The Warriors of Light, 1.0 edition). If you happened to be a legacy player, you pick up FFXIV 2.0 as that. (Which is why we kept our equipment, levels, items, etc).
So yes. The events did happen. But people don't really clearly remember -exactly- what happened as it happened. But they can certainly see the aftermath of whatever -did- happen.
