I'm sure most of you here know that many ancient artifacts have been unearthed around the world that do not fit into the accepted theories of human history. Take a look at two such artifacts found in Southeastern Arizona in the past decade at the link below. They appear to be Oldowan Tools, ancient stone tools used by such proto-human species as Homo habilis and Homo erectus. Yet, history says these species were never in North America. So how do these artifacts get into a dry river bed in Arizona, USA??? I will be interested in reading your observations, theories, and opinions.
Why and how could ancient people have dragged railway cars sized block of stone and stack them up together to form these amazing constructions? Why is it that we have found thousands of Pyramids scatter across the globe? These structures are truly a global phenomena that have puzzled archeologists for centuries.
