Did hunters-gatherers (in general) have a religion?

Yes. Generally speaking, hunter-gatherer tribes do have a religion.

Each tribe typically has its own religion and myths, so one has to be careful about stereotyping or over-generalizing the vast range of beliefs and religious practices found in such tribes around the world.

Nevertheless, it is true that many hunter gatherer tribes practice a religion that involves both animism and shamanism. Sometimes hunter-gatherer religions are collectively referred to as "animism," but that's a bit of a misnomer because "animism" is a specific belief that is part of many hunter-gatherer religious traditions, not a proper name for those religions themselves. Nonetheless, some anthropologists for the sake of convenience collectively use "Animism" as a name for those religions in which that belief exists.

Animists believe that the natural world has a spiritual component. For example, animals, trees, and even rocks may be inhabited by some sort of spiritual essence. Shamans (also known as "medicine men" or "witch doctors") functioned as healers and intermediaries between the tribe and the spirit world. Besides healing, they may organize or preside over religious rituals and ceremonies.

Hunter-gatherer tribal religions are actually quite important in cultural anthropology because modern religious practices ultimately trace back to prehistoric hunter-gatherer religions. After all, our distant ancestors some 15,000+ years ago were all hunter-gatherers. For example, the concept of the priest is traceable back to the hunter-gatherer shaman.

Yes, they often did have religion. Just look at Native Americans for many examples.

Yes, probably. Animism is generally thought to be the earliest form of religious thought, and was almost certainly practiced in some form or another back into pre-historic time periods.

Yes. We see this particularly in burial rights, which have religious overtones. Different peoples, in different times buried their dead differently, but the use of "grave goods," that is, things useful in the next life can certainly be found pretty often. We do not know a lot about these ancient religions, but, we can tell a little from the ones that exist amongst hunter-gathers today, or those who were so in recent (100-150 years ago) history. E.g., in northern Canada. I lived with a northern shaman for 7 years, and she certainly had beliefs, which remained even after she became Christian.

How would we know? They hadn't invented writing yet. It's thought they had animistic beliefs and shamanism, but what they called it and exactly how they practised can't be known.

I've always been fascinated with the earliest of history.. so I've done a lot of research and prayerful questioning and pondering.. What I've learned is I think all the 'mother goddesses' were (originally) faint memories of Eve.. passed down.. Who Adam called "the mother of all"..

I think Cain embodied that first form of the other religion.. (which has taken many forms.. all untruth as opposed to truth.. even when blended with truth. Why was Cain's offering not acceptable to God? I think because it was an outgrowth and part of that idea of "and you will be like God.." (Ascension, apotheosis, "I will"/self interest) - Remember Satan via the serpent said "can't you eat of every tree? ..surely.. you won't ..die?" And man is then thought to be immortal.. and this belief is so solidly anchored in mankind's psyche.. But the bible talks about resurrection.. eventually of all.. "every knee shall bend and all families rejoice before Him.." The whole problem of course being the ability to make choices.. an offshoot of thinking ability.. I believe the Cainites perished in the flood.
