I see a lot of people here have a beef with God. No, don't say you do not believe in God because you don't talk about leprechauns farts, because it is so stupid you don't need to explain or attack that belief.
Why am I supposed to accept someone's belief in god, when I don't simultaneously accept someone's belief that purple unicorn farts cause erections in leprechauns?
Hmm if there is no God then good and evil is relative , you are right you don't need to respect anything, we are just a fluke, we have no goal , and don't start talking about moral law. The moral law is put into us. But if there is no one to put it into us then there is no moral law in us and then all is relative.
Of course this is the best example why philosophy fails, because someone will post a better philosophy and beat mine, and so on.
But there is one thing that we all have. That is HOPE.
