Why do airplane wings have round leading edges?

Question

I don’t understand all the internet explanations using terms like “Range of attack” “Stall speed”

I’m trying to understand why it matters that the wing has a blunt front, if just angling a flat sheet slightly upwards should in my theory still lift it up at speed.

Although those round edges intuitively make sense somehow, i just want to understand why they work.

As I understand it, the sharp edge would require a near perfect wind angle/airflow. The blunt rounded one allows for more play withe the angles, hence “range of attack”. Essentially it makes it more stable and easier no use
