The purpose of this book is to describe the causes of deterraformation and how this process precipitates the terraformation of other worlds. It discusses why billions are being invested in the latter as opposed to the former process. The terrestrial or grounded culprits identified for the drastic climate changes being experienced are greedy polluters and their surrogates who sell representative government to the highest right-wing bidder, as well as extraterrestrials vested in deterraformation of Earth to further extract its resources without interference. It presents Exo-theories that the natural and human causes of global warming are extraterrestrial by design and continuous contact. The history of such contacts is used to explain that mankind's existence is an outcome of numerous extraterrestrial agendas between competing off-world and multi-dimensional beings. This book tackles the question and seeks to extract answers to the causes for global warming from human to extraterrestrial activity. It examines the extent of climate change and its implications for the continuous habitation of mankind on this planet. The book shifts to theoretical constructs for the terraformation of other worlds. The most selected of the worlds, Mars is the subject of what steps need to be taken to make this planet the first to habitat considering its extremely cold and dry climate and thin atmosphere. This study extracts lessons from Earth's greenhouse effect. It identifies the leading emissions and the chemicals needed to warm the Martian atmosphere and theoretically cool the atmosphere of Venue. The book explains how the politics of greed lead to the deterraformation of the Earth resulting in planetary havoc. In doing so, the vivid definition of terraforming and deterraforming is given. In making other worlds in the Solar System habitable for colonization in the wake of the destruction of Earth's climate, the cost, candidates and plans for this transformation are analyzed and evaluated. Besides the greed of the elites and their political surrogates, this book looks at extraterrestrial intervention and the alien agenda imposed by secret agreement with US presidents and Majestic 12 in relationship to the deterraformation of the Earth. Some Exo-theorists believe that it is in the interest of some of the 130 alien groups competing for control of the Earth to make this planet uninhabitable for homo-sapiens so they can exclusively occupy and extract resources at an unimpeded rate. Allegedly, these aliens can breathe better in a highly carbonized atmosphere like Mars and deterraformated Earth. The treaties and negotiations paved the way to this alleged invasion grew out of the Roswell Incidence and alien surveillance and interference with nuclear tests during the Cold War and afterward. The book peruses through the history of alien contact from the present to the seeding of mankind and civilizations on Earth. The influence of culture and civilization is analyzed with respect to alien influence. DNA studies are highlighted to provide evidence that homo-sapiens are seeded by aliens, particularly their intellectual design. The book makes a case that hybrids and those surrogates of aliens were responsible for cultural developments of the Renaissance and Enlightenment. The book travels further into the past to how extraterrestrials originated religion and science. The lessons derived from their contact include the Big Bang Theory, Quantum Theory, and String Theory, which were not completely developed until the 21st century. How this knowledge was taught to the ancient Dogon-Egyptian population and passed on to modern man is explained. The African Mystery System that conveys this cosmological knowledge is identified through its medium the Masons, including the Founding Fathers of the United States of America (USA) and other geniuses ahead of their times.
