The Being came into existence in the smallest amount of time possible.
Perhaps it was conceived elsewhere and ‘born’ here. Perhaps it was always destined to exist at this point, or perhaps it was random chance.
Whatever the circumstances, The Being now existed. And it was the most powerful being that could exist, able to shape all matter to its whims, instantly. Nothing else that existed could stop it.
Thankfully however, its first conscious thought was that it was in pain and didn’t want to be, so it went out of existence just as fast as it had come in.
