Gears are a way of trading power for speed, or the other way around.
A human body, just like an an engine, will work best at a certain pace and resistance, you want to keep turning the cranks at beetween 80-100 turns/minute.
If pushing the pedals becomes so heavy that your pace drops off, switch to an easier gear. If pushing the pedals becomes so easy that you have a hard time keeping up, change to a heavier gear.
The more gears you have on your bike, the easier it becomes to always find a gear that allows your body to work as well as possible, regardless of if you're heading uphill, downhill or on the flat.
The number of gears you can use depends on how much variation there is to your riding. If you ride somewhere flat, you are likely to spend almost all your time in a fairly narrow speed range, and you'll only need a few gears to cover that. If you ride somewhere hilly, your speed range becomes greater and you'll need more gears to always have that fits the situation.

Bikes have gears so you can go on different terrain. one gear is for flat roads, one is for hill climbing, one is for going fast, etc. not all bikes have the same amount or type of gears, so be careful!!
The gears on a bike are used for switching the speed!
Humans, and engines, works best at a certain rate of turns and a certain resistance. With gears the rider can keep turning the pedals at that rate and resistance regardless of if he's going uphill slowly or downhil fast.
