So like, if sand can be used as the first "ingredient" of a CPU, is it possible to use other variants of sand? Or is there only a very SPECIFIC kind of sand used for CPU creation?

So you can't use fine sand from the beaches of a tropical island or black sand in Iceland?

Sorry if this is dumb, I thought it'd be humorous if you can use any sand as the first resource for building a CPU since they literally come from that source.

Sand is not per se the raw resource for integrated circuit production. More specifically, it is silicon dioxide, also referred to as quartz. Quartz is often found in sand, but sand does not necessarily include quartz. As far as I know, the quartz for semiconductor lithography isn't usually extracted from sand, but rather from proper pit mines.
