At that time, there was no writing, no alphabet, no letters, which they could use to describe daily or special events.
So they used painting to do that, since it is easier to describe something by painting the same thing.
You can compare our ancestors with babies: they start by painting and drawing stuff, and by the time they can perfectly communicate with drawings you start teaching them letters and writing.
[Update] They believed in sympathetic magic, which was painting an animal to capture it's soul, and improve their luck during a hunt. This was significant as they were hunter-gatherers, and it was of such importance to them that they gathered the resources to make paint (berries, leaves, blood, urine) and made brushes out of sticks, human hair, and tree sap.
It's not known for certain why the cavemen painted their hands on the wall. In some cases it is thought to symbolize numbers, and in other cases it seems to be more like a signature, as an artist might sign a painting.
Dry latex paint can sometimes be reactivated with water because latex paint is water-based. When water is applied, it softens the paint's surface, making it easier to wipe off. This is especially common with matte or flat finishes that have not been properly cured.
