Having worked thirty-five years as a process engineer and manager in the chemical industry, Henry Pfeffer decided to retire in 2009 to pursue a second career as a high school science teacher. While preparing for the teacher certification exams, he reviewed current college textbooks in physics, biology, astronomy, and earth science, and he was surprised to discover how much our knowledge in each of these scientific fields had progressed over the last forty years. As an engineer, he solved "real-life" problems by learning how to piece together bits of data to create mental models of chemical processes. He subconsciously followed this same approach as he studied subjects ranging from astronomy to cellular biology. As Pfeffer organized all of this information into a timeline, a detailed picture emerged of the extraordinary process required to create human life on Earth. He felt compelled to share this picture with others. The author's goal in Human Creation is to stimulate new ways of thinking about the origin of human life. He would like readers to recognize we are here on Earth today as the result of a process carefully planned and precisely implemented by a creative God, and to understand why God's love for all of humanity runs so deep. He also hopes his arguments, along with the information he provides, will convince others that although evolution is a necessary characteristic of all living organisms, it is not the reason why human life exists on Earth today. Those who believe that life on Earth was created should find the author's arguments exciting, while those who are convinced it evolved are bound to search for flaws. Either way, this book makes for a fascinating and challenging read that will appeal to a wide-ranging audience as it goes right to the heart of the debate.
