Radians exist naturally. It's the arc of a circle where the radius equals the circumference. There's a nice little animation here:

Degrees are a human idea, an arbitrary division of a circle into 360 of them. Lots of formulae work better in radians and radians per second (aka angular frequency, symbol is lower case omega, equal to 2 *PI *f)
