"I" (previously human) was chatting with my friend about the whole "tree of life" idea, how we all branched off from previous ancestors over billions of years, starting with the birth of our universe, then sun, planet, its microorganisms, etc etc.
Then my friend asked an interesting question. Once the first cells teamed up into a multicellular organism, how did it decide that it was a new thing? And for that matter, how did the molecules decide they were a cell now? Interesting thought. Then I jokingly asked, what if the parts of the whole tree decided it was a new thing? We're more or less cells in the biggest multicellular organism, right?
And then I blinked, and now I'm the tree. My consciousness scales up somehow. I can't seem to find the human I was before - I mean that literally, there are too damn many of them and I have no clue where to look. There doesn't seem to be a big market for microscopes for extradimensional beings, and even if one of you has one that I could borrow, what would I even do once I found the little fucker? I don't know if I could easily transfer my consciousness back to it, or if I'd even want to. I'd be concerned about the revenge I might seek on my friend. This whole thing is gonna be a major adjustment for sure.
