Umm, because 90% of your listening audience would not know what the hell you
just said? As a primary student, I didn't give a damn about lift
coefficients and wouldn't know an angle of attack from an attack onn my
angle.

If you don't have even a basic understanding of how a wing
works, you are a prime candidate for any number of fatal
accident scenarios from departure stalls at high altitude
airports to spins.

All I needed to know what that at a certain speed, the plane will
stop flying and fall from the sky.

The wing will stall at any attitude and any airspeed.
Knowing the "stall speed" is not enough. If you don't like
the proposed explanation, it can be as simple as:

As the front edge of the wing is tilted up, the wing
produces more lift up to a limit called the stall angle. As
the front edge is tilted up more than the stall angle, the
lift begins to decrease instead of increase.
