Real science came out of the European "Enlightenment" era - including the "Scientific Method" which required "evidence" to support any claims made by scientists. Prior to science - the Church was a first organized attempt (much based on ancient Greek ideas) - to explain nature and how it behaves. The Church, to this day, does not like science in many areas - since science is based on facts derived from evidence and Church dogma is based on what single men claim is reality, without any evidence whatsoever - you must have "faith" to believe these men, who authored holy books, were somehow gifted or their eye witness testimonies were accurate (called "circular reasoning"). Science does not expect you to take a scientist's "word for it" - scientists must have valid evidence to support their claims - which will be scrutinized by many expert scientists - in fact - the Scientific Method requires that any scientist making a claim about nature - must try to disprove his or her own hypothesis (educated guess). This is not true of religion - you must "believe" based on another human's word as accurate - the proof authors of holy books give - is simply that what they claim is written in the holy book - often what they wrote themselves. This is often a point of contention (disagreement) between science and religion. Given this fact, however, many scientists are religious - they have somehow been able to make two conflicting arenas of thinking - agreeable - a mental trick that resembles Orwell's "doublethink" - from his classic novel, "Nineteen Eighty-Four".
Science has been a human endeavor because it takes human curiosity to ask the questions, human logic to design the experiments and human ingenuity to incorporate the results into an evolving model. Science demands that we work hard, although when our demands go down, we also tend to lower our efforts to achieve some goals. At times, people put themselves under pressure to achieve what others have, or when we want to rank ourselves with other people we value in our lives.
