Are humans animals or aliens?

According to Linnaeus classification of living world, human beings are among the vertebrates and we are in the group of primates where our neighbors are chimps, gorillas and orangutans. It's true! Genetic evidences show 99.6% of human and chimpanzee DNA are the same. Like the cat and the lion, we are relatives with the apes. But this DOESN'T mean that they are our ancestor. We are cousins...

For me, accepting that human beings are animals is not a hard thing because we live the same way: we eat with the mouth, we see with the eyes, we walk with the foot... etc. So where is the difference? We are the same.
