It's possible in the past the 5th element was used quickly enough that the evil was stopped very far from earth and other planets.

Who's to say it hasn't been stopped far away enough that we don't see it? Who says it goes to Earth specifically every 5000 years? Was the Earth's moon the result of evil's first appearance? It can't be, unless the Earth never had a moon in the 5th Element universe until 3000 BC. So shouldn't there thousands of moons orbiting Earth if evil has showed up every 5000 years since life began? Cornelius himself said that wherever there is life, the evil brings death. When Leeloo defeats the evil, it is rendered as an inert moon orbiting the earth.

Every 5000 years the evil returns and every 5000 years it has been stopped by the five elements, or there would be no life on Earth.How do you tell the difference between the wind and water stones? Is there a 'this way up' indicator that I missed?.Per wiki policy, Spoilers Off applies here and all spoilers are unmarked.
