A Debating Strategy
     A common tactic among  evolution denier tactics is to assault one with a barrage of varied questions, hopping from topic to topic, gloating and scoffing when they eventually find one you admit you have no knowledge of. To counter this tactic one needs good working knowledge of physics, micro-biology, planetary science, zoology, paleontology, genetics, archaeology, theology, chemistry, philosophy, geology, and advanced mathematics. A daunting task, and I've likely left a couple out.
     I suggest a different tactic. Suppose we turn the tables and force them to answer our questions. After all, creationism is a science, isn't it? Ask them to explain fossil stratification, ask them to explain why moles have subqutanious eyes, why fish would drown during a flood, why stars that are vastly older than 10,000 years have had time to shine their light on our planet.  Ask them how creationism integrates with the rest of science as evolution does, ask them why a "designed" creature as cute as a rabbit would need to eat it's own droppings for proper nutrition.
     Don't accept the "God knows, even if we don't" answer.  Theirs is supposed to be a science, and science demands answers.
