I'll take a stab at providing some context, but I think you are looking for a simple answer to a much more nuanced topic. The concept of polytheism vs. monotheism is kind of a false dichotomy usually used by some cultures or traditions as an excuse for violence against another. For example, the Muslims often justified early forced conversions against Christians for practising idolatry (having images of the saints) and polytheism (worshipping a holy Trinity). Begging the question of whether Christians are polytheists or monotheists. Apparently, two different people had two different answers to that question in this example. Also, many cultures had traditions surrounding spiritual or supernatural phenomena to whom they prayed or offered sacrifices, and we might now call it a god, but if a man prays to a snowy mountain for it not to have an avalanche while he's crossing it, do we consider the mountain a god, now? Even if the man just thinks the mountain itself is capable of listening?

Before I answer your question with just a bunch of questions, let me just say that the vast majority of cultures featured a wide variety of spirits and supernatural entities which I would argue leans more towards a polytheistic type of culture. That being said, even many cultures that claim monotheism often lean more towards a type of monolatry which is the worship of a single god among many. For example, Christian traditions often include angels or saints who can be prayed to for intercession or believe in a Satan who possesses many god-like powers even if they are inferior or subservient to the primary god (which are features we see in other polytheistic traditions). As someone of Irish descent, my grandparents told me stories of the faeries, and there are people living in Ireland who still believe and pay the traditional respects to the fair folk even though they are still traditionally catholic (bridging between polytheistic and monotheistic traditions). Also, the Hindu tradition features a huge plurality of gods, but, also, they state that each of these is only a facet of one singular deity which encompasses all of creation (so, are they more monotheistic or polythesitic?). Also, many polytheistic traditions feature one singular creator or originator deity who may have died or created everything and then isn't really very active afterward: see Pangu, Ilmatar, Ymir. So, I would say there are a wide variety of traditions with some features of both polytheism and monotheism. I would say, generally, polytheism in terms of a plurality of supernatural entities dominates most cultural traditions. I would say that monotheism or at least monolatry either emerges from or is embedded in some of these traditions, but often still might feature many aspects of polytheistic traditions in the form of practices or superstitions.

I think if you want to learn more about any of these ideas or concepts, you should consider asking a much more focused question so you can get a better answer from a topic expert.
