They originated from the Earth.

Answer

We now know that man evolved from our predecessors over a period of several million years. Archaeologists have unearthed numerous remains of the early hominids who preceded us.

The term "human", in the context of human evolution, refers to the genus Homo, but studies of human evolution usually include other hominins, such as the australopithecines. The Homo genus diverged from the australopithecines about 2 million years ago in Africa. Several species of Homo evolved, including Homo erectus, which spread to Asia, and Homo neanderthalensis, which spread to Europe. Homo sapiens evolved between 400,000 and 250,000 years ago. Most scientists favor the view that modern humans evolved in Africa and spread across the globe, replacing populations of H. erectus and Neanderthals. Others view modern humans as having evolved as a single, widespread population.

Humans (homo sapiens) are the present representative of the genus Homo as it has evolved from earlier forms (Homo erectus, Homo habillis et al.)

Note I did not say we are the end of the evolutionary process, came from more primitive forms, the result or other terms to suggest we're the best or the final step.

Since our earliest ancestors we have been adapting to fill an ecological opportunity. This has led to us presently having larger brains, an erect posture, colour vision, an inability to create vitamin D from our food, a vestigial appendix and many other characteristics.

We've beaten out competitors (e.g. Homo neanderthalensis) At times we have been almost wiped out as a species. Presently we are flourishing on every continent.
