The previous inhabitants of Eureka all got dunked in the Lifestream which killed them since that is where souls go when they die. When Eureka, the primal, forced the Isle of Val out of the Lifestream, those souls didn't leave the Lifestream with it.
There is plant and animal life on the island, both and monsters count just the same as being able to be transformed in one aether based direction as seen in effect on the first with the lesser Sineaters formally being animals and monsters. Plus there is the case that the first three zone bosses were likely humans before the island was taken in the Lifestream before being turned into or merged with elemental monsters.
