I challenge you on that. Other beings, sufficiently advanced, could understand chemistry and mathematics. Those are objective things. If there is an objective definition for morality, a scientific one, then that definition can apply to all intelligent sentient life. I agree with you on a thousand points, but I challenge you that morality is purely a human construct, because you are basing that on observation alone. If there are underlying universal principles, they would apply to everyone and everything that it applies to, human or not. I don't have any proof of that, but we are talking theory. If you want a scientific morality, based in reason, then you're talking about one based on things which are not merely human opinions, but functions of our existence. If there is ever to be any morality based on something besides anger or joy or belief, which does not equal morality, then it has to be based on objective things.
Objective things exist outside of humanity and would apply to all sentient life.
If we one day met an intelligent, alien species, but they enslaved other intelligent beings against their will, we might have a universal basis for showing them why it is immoral, based on universal, actual principles.
I wouldn't agree with any form of moral theory was broken simply because now we aren't talking about humans anymore. Then it simply becomes our opinions again. I don't think that science should be based on solely that.
