Why does combustion engines need multigeared transmission while electrical engines can make due with a single gear?

So trying to figure out why electrical engine only needs a single gear while a combustion engines needs multiple gears. Cant wrap my head around it for some reason

EDIT: Thanks for all the explanation, but now another question popped up in my head. Would there ever be a point of having a manual electric car? I’ve heard rumors of Toyota registering a patent for a system which would mimic a manual transmission, but through all this conversation I assume there’s really no point?

It’s not easy to control the rotation of an engine as it is predetermined by the manufacturer to be of certain power. So we need to use gears to get the control of the rpm(s).

But in electric motors, you can just use more current or less current to vary the rpm(s). Also, you can go reverse by just inversing the current.
