Christians have a much more sophisticated view of the universe than the author must realize. Also, there are some flawed thoughts held by the author concerning history as it is recorded. The idea that during the Middle Ages Christians destroyed scientific progress is not supported by historical research. Since you mention the scientific method, Roger Bacon, a Franciscan friar and the father of the modern scientific method existed during this time period. Comparing what is going on now with the followers of Mohammed to the Crusades unfortunate shows the author should spend some time studying both. As for the creation of a global community based on logic, reason, science, and compassion you have just described the the life of powerful follower of Jesus.
