Evidence such as ancient texts, carvings, ruins and tools have been found by many archaeologists. Examples of these anomalies include the findings of Michael Cremo and other archaeologists who found not only ancient objects, but also human skeletons and skulls. In Cremo's “Standford University Lecture” he exposed his ideas and discoveries on Forbidden Archaeology; then, it describes other investigations by other archaeologists and geologists who also believe that human origin began thousands of years ago. One investigation that Cremo talks about in his lecture is the discovery of a human jaw by English archaeologists in Foxhall, England. Cremo mentioned that "the jaw was found deep within the Earth's crust in the Pliocene of the Falesia Rossa", which the geologist suggested was two to three million years old (Cremo). Other discoveries include Mary Leakey's discovery of a human footprint at a site in East Africa. The footprint was said to be "370 million years old" because it was buried deep within a layer of "volcanic ash"; furthermore, the Leaker also stated that the footprint resembled a “modern human foot” (Cremo). Investigations and evidence such as artifacts, footprints, and skeletons are all evidence that humans lived on earth thousands if not billions of years ago; however, this is not all,
