So I was on a train and got curious how waterwheels and wind turbines and everything of the sort make electricity so like any normal person would I searched it up. And on google I kid you not all the responses were “it spins the generator making electricity” like what am I dumb or does to at make no sence and explains nothing please help.

You can’t understand generators without first understanding (or at least accepting) Faraday’s law. If you move a magnet near a conductor, you induce a current in that conductor. You might ask “how?” and “why?”, but just go with it. Magnets and electricity are related, and one can create the other.
Take a long piece of wire, and wrap it into a coil with a hole in the center. Now take a magnet and move it through the coil. You will see a current forming in the wire, transporting electrons from one end to the other. Move the magnet back and forth, and you’ve created an alternating current source. Attach the magnet to something that moves back and forth, and you’ve just made an electric generator.
Spinning is similar, just instead of moving the magnet back and forth in the coil, you spin the magnet inside the coil.
