Even though he was basically being idolized as a god, Sobek didn't notice anything.
The reason was simple: the city of Thirkiom had just over ten thousand inhabitants. Furthermore, the Neanderthals had no contact with other cities: due to the large predators it had never been possible in history to establish trade routes. Even the Homo sapiens sapiens had never had contact with other tribes before the advent of firearms.
As a result, the fame points Sobek had earned were just ten thousand. Perhaps he would have noticed that little change when he was still a Spinosaurus aegyptiacus, when the fame points bar peaked at one million, but now that that bar had expanded to one hundred million a change of only ten thousand points remained unnoticed.
