Maybe this could be key and its as i have said in other threads they could go the route of the supreme creator to be some kind of Machine that has a single brain in the center but then it is some Bio Mechanical Machine and Architecture that kept growing and growing, like say how Coral does...
And this replicating growing Bio Mechanical Machine could create many kinds of life and also absorb many kinds, i think that would be a cool idea.
If this machines prime purpose is to create organisms to then go and extract genes from other organisms so that this machine can improve and evolve itself and also use the best parts of what ever genomes it gains to produce even more advanced and efficient organisms to carry on and to its bidding.
