So in Vol. 3 we learn that the HE created the Sovereign race of people and we see them as an established civilization back in Vol. 2, which takes place in 2014. And he also made rocket who is an adult by the Vol. 1(also in 2014). He is also know to have created many other civilizations and life forms by Vol. 3. So, how old exactly is the HE? He’s probably just an average age, but the fact that the Sovereign civilization was already well established makes me think he is probably an extremely older being, as he doesn’t really appear that old by Vol. 3, and the fact that he had to have made the Sovereign before rocket, as rocket had to have aged shorter than humans as most raccoons do, so I doubt he could’ve created the Sovereign in between rocket escaping and us seeing him in Vol. 1.

Im probably looking too much into this, but I thought it was an interesting discussion.
