you want to know why?

Its not a word
That’s fine, we don’t believe in you either.

you know what else isn’t a word according to Microsoft Word/Google Chrome?
peroxisomes, Endoplasmic Reticulum, glycolipids, glycoproteins, actin, cytoskeletal, ecdycis, aceolomate, euceolomate, psuedoceolomate, coelom, panarthropoda, hemocoel, arthropoda, porifera, metanephridia, protonephridia, mollusca
these are words I had to manually enter into Word as actual words. this is only a very small sampling from a single 100 level biology class.
But if you want to go with your logic life on earth does not exist because without actin cytoskeletal elements cannot be made and cells would collapse in on themselves. Actin is also necessary for other reasons, microtubules made of actin are used to corral chromosomes during eukaryotic cell division, if they were not present the chromosomes would have no way to get to the opposite sides of the cell, and then the daughter cells would have the wrong numbers of chromosomes and the lineage would either end or be all sorts of fucked up.
tl;dr: science says FUCK YOU
