In this essay, I will talk about something that has been considered for centuries, the question or problem of evil. Apart from the fact that various philosophers, theologians, and people in general deal with evidence of God's existence on a daily basis, such as the ontological, cosmological, and teleological, there is one most obvious indications that God does not exist, and that is the existence of evil. The arguments show in more detail the problem of the existence of a perfectly good, omniscient and omnipotent God and evil. I will begin with a closer look at what is really considered the term God, what definition people use, and what characteristics they use to describe such a being. After that, I will talk about where evil actually comes from, why it exists at all, about the two types of evil that exist, and about the argument that if there is evil, it follows that God does not exist. I will also talk about how philosophers and theologians respond to the problem of evil, and I will list the arguments put forward by theists, and the counter-arguments for their arguments.
