Final answer:
One of the strongest arguments against the existence of God is the apparent incompatibility between evil and the existence of an all-powerful and infinitely good God. The philosophical problem of divine omniscience and human free will also argues against the existence of God. However, it is important to note that the non-existence of God cannot be proven scientifically.
Step-by-step explanation:
One of the strongest arguments for the non-existence of God is the apparent incompatibility between evil and the existence of an all-powerful and infinitely good God. Many theologians and philosophers have questioned why a deity with absolute goodness, power, and knowledge would allow evil to exist in the world without intervening to combat it.
Another argument is the philosophical problem of divine omniscience and human free will. If God is all-knowing and knows the future, how can humans have free will to make choices? This raises questions about the nature of God's omniscience and its compatibility with human agency.
While there may not be scientific evidence for the existence of God, it is important to note that the non-existence of God cannot be proven scientifically either.
