I am curious, Oristar. You have read the books and have thought about this...
How do you form any objective moral beliefs from science?
Morality is based on ideas of "fairness", and "justice", and the "common good", and "natural order" and all sorts of ideas that only exist in the minds of human beings.
Nothing in nature cares about fairness. Some worms are eaten by birds, others survive to reproduce... often whether an animal lives or dies is based on where it is born, or on the color of its skin. We care about justice.... but justice would mean that the Zebras would kill and eat the lions. Nature is happy to have slavery, and rape. Mates are killed and eaten, food supplies are raided and stolen.
In truth, the Universe doesn't care at all about any of this. Next year a large asteroid could show up and wipe it all out... killing the human race. Would that be "immoral"?
Morality depends on supernatural beliefs. A supernatural belief is a belief in something that can't be shown by science. If you don't believe that human life is sacred, then how can you be against murder?
And yet there is nothing in the Universe that cares about human life other than humans (and maybe dogs... but they were specifically bred by humans to care).
