I feel like this part of evolution is kind of skipped over by historians. The more I think about it the more it hurts my brain

Note: Historians wouldn’t be looking into this question, so the fact that it’s skipped over by them is not surprising. Cellular and evolutionary biologists would be looking into this question.
And the truth is that, since we don’t have a time machine, we cannot possibly know how it DID happen, we can only give educated guesses as to how it might have happened.
For Example: It makes sense that cells which formed membranes and walls would better survive their environment due to the protective layers, and would be more likely to multiply. It makes sense that a bunch of cells which clump together would also have a greater overall chance of survival and therefore replication due to some cells providing protection to others.
Replicate that over and over again into increasingly complex “clumps” and you eventually get something we’d call a single multicell organism as opposed to a large cluster of single celled organisms. Where exactly is the line that marks where is stops being a group of single celled organisms acting cooperatively and starts to be a multicellular organism? Hard to say exactly.
There are other theories, that’s just a very crude summary of one.
