Title help???

I'm trying to get back into writting, finally, and I do have a couple of very interesting stories to put up, but I need some help with the titles...

The first I know the name it's supposed to mean ALL THE ART IN THE WORLD, but I can't know if it's tout l'art du monde or tous l'art du monde?

It's about Paris 68 and the revolution of art and thought.

The second one I ain't sure
It's a bit of a polemical story, about well, about god, but not like god allmighty, but a lonely sad, confused creator that has not clear if he created everything. Basically it's the romance of god and the devil.... Short story more reflexive than active....
No idea what to call it though...
