Sounds like Holy/Lifestream/Meteor.

Let me fly above the earth.

Holy needed to be high above the Planet to destroy Meteor.

The earth splitting everywhere.
Such a terrible event.
Total random destruction.

Sephiroth using Meteor to damage the Planet for his own plans.

My Messiah, please heal the earth
Before God starts from scratch.

Sephiroth was planning to absorb the Lifestream's energy used to heal the Planet to become a god.

I fear I shall not be reincarnated now.
And so the universe will only remember the Earth.

After Sephiroth absorbed the energy of the Lifestream, the Planet would most likely die.
