There is no evidence, nor can any rational explanation be made, in support of a universal morality outside of the realm of homo sapiens. No morality exists on the moons of Jupiter, until a live human being sets foot there. Morality is a way for human beings to associate with one another and the outside world.
Since you've cut and pasted here again, we'll just go down the list on the second quote, since argumentative ventriloquy seems to be your preferred method of communication:
1) No gods worth having exist. - Subjective, "worth having"
2) No life after death exists. - I would say there's no evidence for it, and science points against mind/body dualism. We don't have enough information.
3) No ultimate foundation for ethics exists. - Disagree, in the sense that there is a foundation for determining health and well being, the minimization of suffering, and the social constructiveness of families.
4) No ultimate meaning in life exists. - Objection, subjective and non-cognitive.
5) Human free will is nonexistent. - This is a deterministic argument, which is philosophy, not science.
Interesting… The US Constitution assumed all human rights were bestowed to us by our Creator through Natural Law . Where do you believe our rights come from? Beyond this, where do mathematical concepts and ideas exist? They are objective, not physical, nor do they necessarily describe anything physical.
