Those are certainly some nice photos. My french is a little rusty, but I didn't see anything explaining how these are formed in nature. Some of those look like naturally formed rocks, whereas others look more manmade. Care to post a link describing how those perfect spheres are formed?

Also of note, I have no idea what conspiracy or ancient civilization these are attributed to, if any. I'm just curious.

The Le site d'Irna has two web pages about natural stone balls (stone spheres), which are cannonball concretions. They are:

2. Stone balls : in France too! [Le site d'Irna].
