The Tower of Babil...

[Storm]

The way the Tower of Babil is described, it sounds like it stretches all the way to the moon, so the Giant would come down to Earth directly from there. But since there's no sign of the Tower on the moon itself, I guess it falls short.

The only way this could work is if the the moon was a geostationary satellite. However, since the moon orbits around the Earth, the tower would be torn apart.

But then again, if the Tower of Zot can exist in mid-air, then I suppose a giant tower could extend from the Earth to the Moon.
