Why did Cro-Magnon people use only a particular spot on the cave wall to paint creatures over another?

Cro-Magnon people likely chose specific spots on cave walls for their paintings due to a combination of factors, including the surface texture, accessibility, and visibility of those areas. The chosen locations may have held particular significance, such as being part of ritualistic practices or serving as a focal point for communal gatherings. Additionally, the environmental conditions, like light and dampness, could have influenced their selection, ensuring the longevity and prominence of the artwork.
