When I was in the process of converting to Islam, after years of childhood bible studies, I went off into the mountains by myself and read the Bible ( and other books too). Sitting on mountains and reading the Bible in the American southwest without distractions was a powerful, enlightening experience. But most important it openly my heart to belief in monotheism and the Creator was the real issue. I found myself simply rejecting verses which contradicted the natural reality in front of me. The reality is creation itself is excellent but dependent, and the Creator would need to be independent, utterly beyond perfection, and certainly above the flaws attributed to him in the Bible. I knew from my previous studies that the Bible made irrational claims against the Creator. In fact, one can read in the Bible that its transcribers admit to "interpreting" stories, much like a biased politican would misinterpret a political event to suit his agenda. Ultimately, I established a belief in the oneness of the Creator, but by having to reject some aspects of the Bible (God turns into a man and is wrestled to defeat? I think not- audhubillah), I sought out a clear way to worship only the Creator and showed Him to be Independent, All Powerful. The Bible has elements of truth in it and introduces humanity to a form of Tawheed which humanity might otherwise not know. Most people don't think profoundly about the Creator. They just go about their lives and accept culture and traditions of their families. Hindus and Buddhists have NO concept of a singular all Powerful, Beneficient, Lord of all the Worlds Who is unlike man or creation. In fact, they and other mushirk nations have concepts of a 'major god', aka a "Great Spirit", the "primary god". However, they have other godlike figures who intercede and intervene between people and that "Great Spirit". And these shirk beliefs tend to focus on the lesser gods as animal spirits, or ancestors, or mythical gods, etc. The Japanese follow Shintoism which recognizes a major "god", but focusses on daily life through worship and intercession of various lesser gods, ghosts, spirits, ancestors, etc. Native American 'indigenous peoples' also recognize a "Great Spirit" major "god", but they too do the same thing- focus on animal spirits, dream figures, ancestors, etc. Hinduism claims a major "god", but of course focus on minor gods including animals. Greek and Roman mythology is heavily referenced in modern Western culture such that many children know of Greek gods through cartoons and TV shows. Zeus is seen as a major "god", but the lesser gods intervene and intercede daily. The real issue is establishing awareness of the One True God who is above imperfection, Who is utterly Independent. Only the Holy Quran establishes this. The struggle is to guide people to think profoundly about life, rather than succumb to prejudices, weaknesses, and failings which keep them in kufr. And Allah knows best.
