Evidence such as ancient texts, sculptures, ruins and tools have been found by many archaeologists. Examples of these anomalies include the discoveries of Michael Cremo and other archaeologists who found not only ancient objects, but also human skeletons and skulls. In Cremo's "Stanford University Lecture", he explained his ideas and discoveries on forbidden archaeology; thus, describes other research by other archaeologists and geologists who also believe that human origin began thousands of years ago. One investigation Cremo discusses in his lecture is the discovery of a human jawbone by English archaeologists in Foxhall, England. Cremo mentioned that "the jaw was discovered deep in the Earth's crust in the Pliocene of Red Crag", which the geologist suggested was two to three million years old (Cremo). Other discoveries include the discovery of a human footprint by Mary Leakey at a site in East Africa. The footprint was said to be "370 million years old" because it was buried deep in a layer of "volcanic ash"; Furthermore, Leaker also mentioned that the print resembled a "modern human foot" (Cremo). Investigations and evidence such as artifacts, footprints, and skeletons can all prove that humans lived on earth thousands or even billions of years ago; but that's not all,
