Would I still be an atheist if I believed this?

[SuperSentient]

There is a scientific hypothesis proposed by James N. Gardner that postulates that there are cycles of cosmic creation within a multiverse in which highly evolved intelligent civilizations (if you could call their society that) have reached a point where they can spawn baby universes. They have enough knowledge in physics that they can tune constants and create a specific "life permitting" universe that allows for specific types of life forms, probably biological structures similar to them. This has already been done long before humans, and our universe is one of those spawned universes. Eventually, we may reach a point where we could spawn baby universes. This means that ET's create universes. This is the selfish biocosm hypothesis.
Now, suppose I accept this hypothesis and start thinking of these natural beings as superior intelligence beings that need to be acknowledged and praised. Could I call them God and then become some sort of theist? I could be a naturalist and accept this, so could it be like a naturalist theist?

I would think the term god wouldn't exactly match this and you would therefore still be an atheist if you are a naturalist.

Ah but then there would the "ultimate necessary" first alien intelligence that started the whole thing many iterations of the universe ago and we call that being god oh and he hates gays.

I could say each ET civilization that spawned baby universes is their own set of Gods.

Would these extra-universal aliens have any method of interacting with our Universe (after setting initial conditions) or would they be confined to their own?

They would create it and leave it alone.

In this illogical dream we got highly intelligent beings that become GODS.
Eh, wait a minute mate.
What about competition?
Why Gods would create competition for themselves?
Doesn't the present going on in this planet explain you that people avoid as hell to create competition for themselves?  

They don't, they just create the necessary conditions for life to exist and civilizations comes much later. The civilizations in the universe they created is independent of them, so, no competition.
