Of course it is not human, it was the God Wars, a war driven by the gods, where humans were the footsoldiers in a seemingly endless war. The various notes from multiple sources suggests that the war was fought very slowly, where campaigns were drawn to a halt and defensive lines moved back and forth at a very slow pace. In addition, there have been hints that the reason why the God Wars took so long was because Bandos made it so. Not only he acted as a mercenary who switched sides when necessary, but as the only t3 god active on Gielinor, he was able to affect the decision-making of the other gods on subtle levels, ensuring they would keep fighting for his entertainment.
Possibly due to the fact that ages have a status quo and a theme of sorts, whether it is a perpetual warfare between the gods, an uneasy state of peace and occational warfare between god empires after Guthix's absence, or the establishment of mankind's dominance. Or because the Fifth Age technically shouldn't be an age but a continuation of the Fourth Age, but was named so by humans of the time. I have a larger theory on that, which also explains why the Fourth Age is exactly 2,000 years, but tl;dr: people in power like King Botolph retroactively assigned a specific date to mark the start of a new age as a sign of the start of human dominance on Gielinor.
In the end, it seems that this suggestion stems from one idea: to make things that for all intentions might not be conceivable by humans, conveivable by humans. JMods themselves have referred you as a person who "explains the unexplainable", or in other words, "makes the unconceivable conceivable". Mostly, like in the case of explaining the workings of magical effects and the Elder Gods, it's fine, but sometimes like this, it isn't good at all. Some things are not supposed to be easily graspable by human mind, and the passage of time in RuneScape's universe could be one of them.
