Here’s a quick one: young earth creationism likes to claim that God created everything out of nothing, but that’s actually a self-refuting claim. Before you can create anything out of nothing, you must first have nothing, and there has never been a time when God had nothing besides Himself. “Nothing” means nothing else existed, not even time. But there has never been a time when time did not exist, obviously. Therefore there has never been a “nothing” out of which God could create anything.
