I like your gift for the obvious. It is entirely possible that the massive and continuing proliferation of Christian sects is that it's core, though unstated assumption, is that God is rational - accessible by human reasoning, proof texting and argumentation. The best scholar, the best bible student and the best theologians are where we turn to craft a "God in our box" based theologies.
Where I might quibble with you is that IMHO one can read the scriptures as man's attempt to capture God in human history. Or one can read the scriptures as a sign that within the world-wide community of mankind, there is an irresistible innate desire for the divine.
Perhaps a very crude metaphor would be salmon. They left the place of their creation with almost no intellectual connection to the rock in the riverbed of their creation....but are drawn instinctively back to their point of creation driven not by logic but by something much more reliable, a sense of purpose and direction.
To many the bible is just 700,000+ pages of confirmation for what they have already chosen to believe. It not about a call to personal meaning, purpose and direction in life, but only the worship of the God in their sect's box.
