I don’t believe they were endowed by God with the sense of law. By the time they were homo sapiens, they already had the capacity for moral awareness, and they were already forming social laws, mores, taboos, and norms. They were not yet aware of God’s specific laws however, so they were not responsible to them. Adam and Eve were the first homo sapiens to whom God revealed His law.
If by “person” we mean “homo sapiens”, it’s easy; if they’re homo sapiens they are people. If by “person” we mean something else, then that depends on our definition of “person”.
Yes.
The Intensification Debate has no impact on whether or not the Australian Aboriginals had moral awareness and their own social order and moral laws long before 3,000 BCE. The fact that they had moral awareness and their own social order and moral laws for tens of thousands of years, is not even debated in the literature. It is certainly not part of the Intensification Debate. No one is writing articles asking “Did the Australian Aboriginals have moral laws 30,000 years ago?”.
I conclude that living beings are morally responsible to God’s law only when that law has been revealed to them and they are aware of it and convicted of it. I don’t see this as a single date beyond which all people became responsible at the same time. So my basis of their responsibility to moral law is different to yours.
No. We also have oral traditions. We also have archaeological evidence of social customs. When we have evidence for executions we know we have a sense of law.
This doesn’t require texts.
