Through logic and useing the human brain, something religion lacks
So are you saying that what determines what is right and what is wrong comes from the human brain? What if two people believe two contradictory things? Are they both right? If two people, "through logic and useing the human brain" come up with two different moral philosophies, what decides which person is correct? Are they both correct?
Learn about morals, they are a societal construct that act as an extention of laws, and laws only came in because of logical thinking and rationality. Someone realised an eye for an eye would kill the whole world. And physcopathic people have little morals, therefore god didnt make morals, because if he did why would he make people deal with such a thing?
