Most of the people who both believe in God and study or research in natural sciences use “compartments” to separate religion and science. That is, they never think of both simultaneously.
It seems that ethics has also to be kept in a compartment separate from science. This is because ethics implies “free will”, that is, that an individual is free to decide what action to take. Science, on the other hand, says that every action is determined by the laws of physics, just like the movements of the planets. Of course, quantum indeterminism has nothing to do with free will. So I will steal or not steal according to the laws of physics, and seemingly can’t control it.
Probably this is the reason why there is no scientific ethics.
