How did cheese come about

I don't think caveman had cheese. Cavemen were hunters and gatherers, they moved from place to place. Only when people began to domesticate milk producing animals such as goats, sheep and cattle did they make cheese. Cheese likely came aout by accident when milk went sour. Remember there were no refrigerators. Even today people make cheese in some places on a daily basis by adding lemon juice to milk and let it curdle. It makes a kind of cottage cheese.

Maybe it's the other way around. The cow have milked the cave man and because of that the cave man discovers it. Unexpected?
