In Terms of Spirituality We Separate Ourselves from Other Animals, But Why?

Most adherents to the world’s religions believe that human beings are, in essence, souls that go on to some form of afterlife when they die.  Yet, as far as I’m aware, there are no such provisions made for our fellow primates, e.g., chimpanzees, nor for other intelligent species like dolphins and whales, nor for our beloved pets, like the fine dog pictured at left.

This strikes me as the height of ignorance and conceit.
