Homo sapiens (us - the species most would consider human) is little more that 180,000 years old. Even if you include all species that taxonomists call 'homo' it takes us back only about 1.5-2 million years. We split from the common ancestor with chimpanzees and banobos about 6 million years ago, but our ancestors then were more like upright apes (at least, I'd think we'd call them that) - and that includes Lucy.
The universe is 13.72 billion years old. Note the two decimal places!
