Why? To restore the Maker.
The entity responsible for creating both humans and fal'Cie.
Long ago, the Maker departed this world, leaving the two races behind.In a sense, human and fal'Cie are brothers; orphaned by the same parent.
So, no, outright lie. Two completely separate beings made the fal'Cie we know and humankind.
And you can say "Well, Cid is wrong/misinformed" but given absolutely nothing hints to that in the actual story, it's still a storytelling flop.
Here is the cosmology as outlined in the cutscenes.
God made fal'Cie and humans.
There is no mention whatsoever of a supreme god (goddess? I believe the second god was the first's son?) who made another god who made two other gods with one making humans and one making fal'Cie.
Also I thought the fal'Cie were trying to revive Lindzei? He's their creator, correct?
