yes because you might burn yourself you nin-come-poop
Yes you do. The filament would burn in the atmosphere so the glass bulb is used to either keep the filament in an inert atmosphere or a vacuum.
You can still burn yourself on the glass though because conventional bulbs five off lots of heat.

Why do you need to have the glass on the outside of a light bulb?
The glass envelope, or bulb, of an incandescent light bulb is needed to hold the inert gas, such as argon, that fills the space. The filament of a light bulb is made of tungsten wire. When electricity passes through it the filament becomes extremely hot and emits light. The inert gas surrounding the filament protects it from evaporating too quickly. A light bulb only lasts as long as its filament lasts.
Could an ordinary glass can serve as the glass bulb of a bulb?
Sure. But before you can use it to provide light, you need to find a way to take all the air out of it, and seal it so that no air gets back in. If air gets into a light bulb, the bulb immediately burns out.
