What difference is there between saying "momentum is eternal" and 
"momentum is conserved"?

The total amount of momentum in a closed system is conserved. 
"Everything", ie, the "universe" is the ultimate "closed system" - 
therefore the amount of momentum in the universe never changes. Ever. 
"Eternal" is an adjective referring to something that lasts forever. 
Like momentum in a closed system.
