What are “phases” in terms of electrical systems?

I work with equipment that operates on three phase electrical circuits. I can’t get my head around the concept of “phases.”

A wrong answer for the sake of ELI5.

Imagine you’re rowing a boat. You have half of the stroke pushing against the water propelling the boat forward, but the other half of the stroke the boat isn’t actually being propelled forward since you’re picking up the oars and getting ready for a 2nd stroke.

Imagine if you add a 2nd rower to the boat who times his rows to “push” while yours are pulling. Now the boat will be propelled twice as much in the same amount of time as the original stroke.

Add a 3rd rower and you have 3 phase power.
