There was no “first” KitKat! What a silly strange deranged heretical thought!
Perhaps you are confusing the (discarded, and rightly so!) Unified Linear Field Theory with the (universally accepted, as it should be!) Unified & Closed Modular Field Theory?
Time ultimately, like all dimensions, is a meaningless loop. Of Kit-Kat’s.
Leaving only one last physics question to settle definitively, by prose, coercion, poison, blade, and projectile: Do the Kit-Kats form a Dünkin torus or a Möbius strip?
Entire schools of sugary confectionary thought hang in the balance!
