notice how the first thing connected to the spine is the brain stem, the part that controls ALL basic human functions and then it adds on and somehow, the top part of the brain seems to be thinking, reason, short and long term memories and whatnot. Anyway, I've been thinking what and how it took to get there and evolution and went to think and imagine the most basic, primitive life that could evolve a brain.

A cell. All those DNAs and RNAs and some other NAs seems to be random. What we see are just cells that hadn't evolve or are in the process of. Imagine the cells that made us and the animals, imagine if our cell ancestors developed random or mutated DNAs from a split gone wrong or something, it all somehow attract each other to form the most basic, primitive brain. The first brain. I imagine it is just your most basic strands of DNAs clustered and chained among each other with genes that specifically sends command.

Then it became a collection center that retains and give out all the information needed for survival. The next million step would probably be splitting itself into copies until mutation occurs to better itself into parasites, worms and other aquatic creatures. The reason I said "aquatic" is because life has to start in a large group where most of the water ends up, bringing materials from fungus, mold, plants and being smashed together? I don't know, but it gotta be something like that.

And then it evolved or "mutated" (i think evolution is just (an?) another word for mutation) and it filled the gaps with crap and they couldn't communicate with each other so it threw a strand of DNAs to link each other which served a purpose until they evolved into brain cells (neurons), who can communicate with each other via electricity. So on and on.

What are the astronomical odds of this happening and when it does happen, how long does it take to transform into us? A couple of billions?

It's interesting how it consists of layer upon layer of fine-tuning and extension, rather than a set of components that were each "made" to work with all the others.
