Even in tribe, people did not share everything. Hunting weapons (means of manufacturing ) were most likely in personal possession. There was also rudimentary trade between the tribes. But as soon as real economy started to appear (and here I use the word “real economy” as system that requires cooperation of large number of people and labor separation) the means of manufacturing (wind mill, pack animals, etc) were mostly in private ownership, could be bought and sold. So, no, not communism.
