Here on the internet people just explain the difference between the two and how you should also apply the handbrake when it gets steep, but why is there even a parking gear in the first place when you can just use the handbrake?

  Interesting question. Especially from the point of someone one from Europe where most cars seem to use regular gears instead of automatics and the park position does not even exists.

Putting the transmission into "Park" engages the "parking pawl" - essentially a metal pin that locks the output shaft of transmission (and thus the driven wheels) in place.

As to why it exists - it is intended as additional roll-away protection that compliments (rather than replaces) the handbrake (which, as the name implies applies actual brakes - usually to the rear wheels). The idea being that if either the handbrake or the pawl fails there's still something to prevent the car rolling away.

Handbrakes, like regular ones wear and thus become less effective with repeated use - and this isn't always immediately apparent to the driver so an extra safety net isn't a bad idea.

  But a manual car can also park with the handrabke while being in a gear. Should the park gear be considered as a perk of automatic gearboxes or is it there to make up for something a manual gearbox would have?

  @Peter You can achieve a similar result by putting a manual 'box in gear when parked - although IMO "Park" has the advantage here since you aren't risking forgetting to take it out of gear and unexpectedly lurching/stalling.
