Earth’s atmosphere is also the reason why we see some stars flickering. The light of the star is constant, but our atmosphere creates diffusion, so some of the photons don’t reach our retinas. Technically, if you and your next door neighbor look at the same star, it’s flickering for both of you, but the flickering is not synchronous since position of observation matters.
