The Answers in Genesis podcast is updated weekdays with a minute and a half audio lesson. The host is Ken Ham. He is well spoken, easy to understand, and he deals head-on with important issues that many people don't know how to answer. The topics that Ken uses are wide and varied. Some include dinosaurs, the flood, stars, planets, comets, death, suffering, Adam, and the six days of creation. I would highly recommend this podcast and it can be found in the iTunes store for free.
