Annunaki breed with homo erectus to create sapiens

The Annunaki arrived on Earth 450,000 years ago looking for minerals, namely gold which they began mining in Africa. When Anunnaki miners became displeased with working conditions it was decided that Anunnaki genes and Homo erectus genes would be engineered to create slaves to replace the miners, thus resulting in Homo sapiens, or man-kind as we know it.
