You don't know how an omnipotent immortal being views time. Billions of years for us could be days for a god. Time is relative to the amount you have lived. When I was younger I recall 3 hour car trips lasting what felt like all day, trips to the store took forever, a haircut felt like a 2 hour affair. Now that I'm older time goes faster years fade away, it feels like yesterday I was holding my newborn child and he's 4 now
