World lore from ARR confirms that there are fragments of Pre-Sundering memories floating around. From the names that Keepers of the Moon use (Most predate the Sundering) There was also talk of time before the Calamity where 'Gods walked Eorzea' but they fled before the First Umbral Era abandoning mortals to the Calamities. To a Sundered, Amaurotines would certainly look like gods in a fractured memory.
