[gaganyaan]

Positing the existence of a deity doesn't get you anywhere. Why is it moral to do what that deity says to? Absolute morality does not exist.

Now, you can quite easily construct a practical morality system: I think murder is bad because I don't want to be murdered. I want stealing outlawed because I don't want things stolen from me. It's really that simple.

This is natural behavior that has proven evolutionarily advantageous for our species, but religion strangely came along after the fact and tried to take credit for it.
