The fact that you found no point or purpose to this book IS the point Camus is trying to make. This book was written as an attempt to explore his philosophy of Abusurdism which states that the universe is chaotic and indifferent to the needs of humanity and that there is no true meaning to life. Depressing, I know, but let me elaborate. Existentialists acknowledged the meaninglessness of life, but at the same time, they tried to find meaning within that very meaninglessness. They believed that you had to construct your own meaningbecause nobody else was going to do it for you. Camus had a problem with this hypocrisy and posed the following question: What if we didn't try to find meaning? What if we fully accepted the meaninglessness of life without resistance and simply lived moment to moment? He was trying to explore this idea with Meursault's character. I suggest you look more into Absurdism or read Camus's journals for more clarity and insight into this topic.
