Without God, we can’t make sense out of life. We are as a people, prone to constantly arguing unending arguments, which leads to no resolve. Without God, there’s no context to interpret the meaning of the reality we live in. Without God, there is no logical reasons whereby to have an objective purpose of anything.
Therefore, without God, things are left to our own destruction by reason of our free will as a consequence. Where we become nihilistic. Rejecting all moral principles and meaning that demonstrate life is meaningful to believe life is meaningless. And to practically live life as atheist. Due to not believing in the existence of God who creating everything with a purpose and meaning.
