At the university level, Jason discovered that an important element in scientific study and the drawing of conclusions was this: that scientists usually are not aware of their presuppositions (i.e. they interpret scientific evidence in light of their existing worldview). It thus made it easier for him to see that intelligent scientists, many who were his professors, can disagree on what the evidence really means, for they have different starting points. So as he read creation materials, he could see that when the evidence was properly interpreted, it always supported the biblical account of creation (even with the thorny question of starlight and time). Most practicing astronomers and astrophysicists believe in the big bang, a billions-of-years-old universe and other evolutionary ideas. But based on Scripture and the best interpretation of the scientific evidence, they are simply wrong, according to Dr. Jason Lisle. He is an astrophysicist with a Ph.D. from the University of Colorado at Boulder, Dr. Lisle is now helping AiG (and the creation movement as a whole) refute the evolutionary account of origins—using his strong science background. He also has designed exciting planetarium programs for the Creation Museum in Northern Kentucky (near Cincinnati, Ohio)
