Actually, it has. There are some natural Cosmic Rays that are actually more powerful and energetic than what the Large Hadron Collider can crank up that have hit the Earth's atmosphere....
And we're still here and the earth hasn't been destroyed.
Unfortunately it's hard to set up instruments around where one of those Cosmic Rays randomly hits, hence the need for the Collider.
According to someone much smarter then me "The incoming Gold Ion [Cosmic Ray], being ‘charged’, would be SIGNIFICANTLY affected/slowed by the randomly oriented charge flux in Earth/Atmospheric matter environment LONG before it finally ‘collides’ with any particular planet-sourced ion."
