Geological Society of America (1983)

The Geological Society of America believes in the importance of using scientific documentation and reasoning. Biological evolution is a particularly impressive example of a principle derived in this way; we geologists find incontrovertible evidence in the rocks that life has existed here on Earth for several billions of years and that it has evolved through time. Although scientists debate the mechanism that produced this change, the evidence for the change itself is undeniable.

The ideas of "creationism," on the other hand, lack any similar body of supporting evidence. We oppose including creationism in science courses in public schools on the grounds that its conclusions were not obtained using scientific methods. Creationism weakens the emphasis on scientific reasoning that is essential to the continued advancement of scientific knowledge.
