eons ago

I've been taught that eons ago our remote ancestors fought the Hunters, and lost, and fled, and were pursued.

Details had vanished eons ago, but something still remained to tantalize imagination.

Eons ago the upper valley was a volcano, when the island of Fatu-hiva was under the sea.

This third dimension we now exist on evolved, millions of eons ago, from a fourth dimension.

In a cold dark universe, whose sun was extinguished eons ago, Amra felt the movement of life, alien and un-guessed.
