And when "we" gained rational thought, we separated ourselves from G-d (Adam hid himself, and then covered his nakedness). G-d cast Adam and Eve from the Garden, and the gulf between rationally thinking humans and G-d has been widening ever since. G-d has made effort (how often is a matter of discussion) to bridge the divide on occasion over time, but not all individuals are "tuned" to this effort and are therefore not readily able to reach across the divide. Fingers and moons, eating and washing, literalists and symbolists. New Age mamby-pamby notwithstanding.
