Why do some clouds appear to be behind the moon?

Some clouds may appear to be behind the moon due to the relative positions of the clouds, the moon, and the observer. When clouds are at different altitudes in the atmosphere, lower clouds can appear to be behind the moon, especially when the moon is low on the horizon. Additionally, atmospheric perspective and the moon's brightness can create the illusion of depth, making it seem as if clouds are positioned behind the moon when they are actually further away.
