There are troubling gaps in human knowledge - we are still unable to marry general relativity with quantum mechanics, and while we can date bread to at least 14kya, the earliest cheese rocks up 7k years later.
It's impossible to credit that bread wasn't invented just so early Man could enjoy a cheese and pickle sandwich, so clearly something is wrong here.
In terms of etymology, as you might expect from one of our foundational foods, it's a direct line to proto-Indo European via all the usual suspects (Old Saxon, Latin).
Interestingly the Frog version 'fromage' has nothing to do with cheese; it derives from the Latin 'forma', referring to any molded food. In this brave post-modern world, we could make a case that pรขtรฉ is fromage.
