Humans are not Primates

It doesn't matter. Humans aren't classified as primates based on the differences; they are classified based on the similarities.

Primate: A mammal of the order Primates, which includes the anthropoids and prosimians, characterized by refined development of the hands and feet, a shortened snout, and a large brain.
So if you are not a primate, which of these things do you not have? Refined hands and feet (do you have paws)? A shortened snout (is your face like a dog or horse)? Large brain (trying hard to pass up the joke here)? Or are you not a mammal?

Perhaps the question you meant to ask was "How do humans differ anatomically and physiologically from other primates?"

From Wikipedia's entry on primates (section "physical description")
All primates have five fingers (pentadactyly), a generalized dental pattern, and a primitive (unspecialized) body plan. Another distinguishing feature of primates is fingernails. Opposing thumbs are also a characteristic primate feature, but are not limited to this order; opossums, for example, also have opposing thumbs. In primates, the combination of opposing thumbs, short fingernails (rather than claws) and long, inward-closing fingers is a relic of the ancestral practice of brachiating through trees. Forward-facing color binocular vision was also useful for the brachiating ancestors of humans, particularly for finding and collecting food, although recent studies suggest it was more useful in courtship. All primates, even those that lack the features typical of other primates (like lorises), share eye orbit characteristics, such as a postorbital bar, that distinguish them from other taxonomic orders.[citation needed]Old World species tend to have significant sexual dimorphism. This is characterized most in size difference, with males being upto a bit more than twice as heavy as females. This dimorphism is a result of a polygynous mating system where there is significant pressure to attract and defend multiple mates. New World species form pair bonds, and so these species (including tamarins and marmosets) generally do not show a significant size difference between the sexes.[citation needed]
Well, I think humans still have most of that, but extreme sexual dimorphism, dense body hair, and tails are conspicuously absent from Homo sapiens
Biologically humans are primates; spiritually they are created in the image of God; and there is no contradiction between the two.
