Well hold on now Raven,
If we wanted to follow the hypothesis that:
"Spira = FF7's distant past"
from the statements Shinra makes about the planet's engergy and refining it/ materia via dresspheres....
Then Spira
would be Gaia.
As FF7's world is named Gaia. Here's my citation from an Advent Children E3 Handout years ago.

It clearly states that the world is called Gaia, and, as my previous train of thought dictates, that would be Spira's name as well.
Consider your mind blown!
xd (Or Square's just ****in with us >,>)Istanbul was Constantinople
Now it's Istanbul, not Constantinople
Been a long time gone, Constantinople
Now it's Turkish delight on a moonlit night
Every gal in Constantinople
Lives in Istanbul, not Constantinople
So if you've a date in Constantinople
She'll be waiting in Istanbul
Even old New York was once New Amsterdam
Why they changed it I can't say
People just liked it better that way
So take me back to Constantinople
No, you can't go back to Constantinople
Been a long time gone, Constantinople
Why did Constantinople get the works?
That's nobody's business but the Turks
