I'm sure that with enough reasoning and debating, eventually everything boils down to Nihilism.
The definitions of Nihilism:
Some people entertain the idea that there is a possibility of God, I've come to accept that there is no God until further notice.Nihilism is the philosophical doctrine suggesting the negation of one or more putatively meaningful aspects of life. Most commonly, nihilism is presented in the form of existential nihilism which argues that life is without objective meaning, purpose, or intrinsic value. Moral nihilists assert that morality does not inherently exist, and that any established moral values are abstractly contrived. Nihilism can also take epistemological, metaphysical, or ontological forms, meaning respectively that, in some aspect, knowledge is not possible, or that contrary to popular belief, some commonly perceived aspects of reality do not exist.
Likewise I do not believe in a universal morality, if eating kids were acceptable to society then there would be nothing wrong with it.
I am still a positive person, you can look at life and think "Life sucks, there is nothing to it." or you can think "Life has no rules! Woohoo!". I just think that it is a superior philosophy.
