To under exaggerate this time, one rectangle is drawn inside a cave and another rectangle is drawn inside another cave 1000 years later. 25,000 years later modern man finds these rectangles drawn on the walls and is astonished?
Is it not just kinda a given that before speech communication there was drawn image communication (like point at images and grunt)?
I mention the 1000 year gap only to point out that they probably moved around and other groups took over caves that were inhabited by other groups before...thus why there are mimicked across europe. ((25000 also being just an arbitrary number for discussion purpose because im not an anthropologist or geologist))

No, not really a given at all.
And those are not images -- they form a symbolic language. If we're merely talking about "point to images and grunt" it would concern drawings of animals and stuff, not abstract symbols. Those are already a kind of language.
And even if it was, having the same stock library of symbols used more or less across continents and ages is important enough in itself.
