Had someone (not a flat earther but someone who questions everything) hold an egg up to a globe, and shine a light behind it. No matter the angle, the shadow would not get extremely smaller than the egg. How is a huge moon casting such a small dark shadow during the eclipse, specificallythe path of totality? I know there’s an explanation, but could you so I can go explain to him like he’s 1?
Thanks!!!

Hold your thumb out at arm’s length.
Close one eye and line your thumb up with something in the background.
Close the other eye and open the first one. Your thumb will appear to move relative to the background. This is called parallax.
In the path of totality, the Moon is perfectly aligned with the Sun. On one side, it only partially blocks the sun, and on the other, it partially blocks the other edge of the Sun.
The Sun is so much further away than the Moon that when you change position on the surface of the Earth, the Moon appears to move more than the Sun does.
