Can we talk about the period in human history where all life that has ever existed was once microscopic cell organisms living in the depths of the oceans for a few hundred million years?

That's neither history nor humanities so, no.

Pre-history is allowed, and everything is humanities.

There's not really much to talk about. Just a bunch of chemosynthetic and eventually photosynthetic predecessors of bacteria and archaea. Most of the time we only have indirect evidence such as unusual layers of organic matter. Sometimes, we're lucky and stumble upon stromatolites and microfossils. We likely will never see anything well preserved due to plate tectonics though. We may never directly find out paleontologically. Our only hope is genetic reconstruction to find our earliest common ancestor. And even then, that common ancestor may have evolved from something else.

You have absolutely no idea what you're talking about, do you? Prehistory is just as much historical as any other history.

Why is history so humanocentric?
