BS!!!
There doesn't need to be any "god" for humans to develop a sense of right and wrong.
It's not a value given down by some imaginary being that there has NEVER been one iota of proof of existence.
Any sentient creature that developes into a society minded being, will start developing processes and rules for that society.
One of which is what is right, and what is wrong, according to that societies average standards for those in that society.
And if that society developes to the extent of electing leaders to manage their society, those leaders will tell the society what is right and what is wrong, dependent on the most good served to the people in that society.
None of it has ANYTHING to do with any "god".
And besides........answering a question with a question is THE most notable scam going, because they don't have any REAL answers for non-believers' questions.
