Dalamud is not an asteroid, whose with me?

SPOILERS (don't know how to make the hidden box thingy).

The Allegan civilization built it and put it into orbit. The Allegan civilization was wiped out in the 4th Umbral Era. 1,500 years has passed between the 6th Umbral Era and this 7th Umbral Era. If we go by this and say they all happen at the same space of time, that would place Allegan civilization destruction about 4,500 years ago. This would mean that Dalamud was put into orbit about 4,500-5,500 years ago, sometime during the Allegan's Astral Era.

And from the wiki:
"Cid also mentions that Dalamud is actually a colossal machine created by the Allagans and is not a natural moon. To activate it and cast Meteor, ancient stones known as Allagan runestones are required."
