I agree with what rob said. On top of that, we construct morals because we are a social species. One human by themselves has no reason to construct morality because it simply does not matter. Once there are multiple people living together in a society, they have to decide how to work together or their society will fail. A society is much more likely to succeed when more people are able to work together.
This is why we see a large variety of moral values across different nations. The differences also have some impact on how well these societies work and how happy the individuals are within them.

I don't believe you. Get over it.
