There's no need to insert divine beings into concepts humans do not understand completely yet, it just adds a whacko incomprehensible divine being that happens to coincide with crazy goat herder Bronze Age rules and customs.
The conscience can be readily explained by guilt being a trait that causes an increase in fitness in the context of societies where cooperation is rewarded, and "cheating" is heavily punished.
Any model of the universe that requires a divine being as a first mover calls for bad special pleading logic where everything needs a cause except a complex divine being (with crazy rules that conveniently change later on), which falls apart when you ask why the universe/singularity cannot be eternal, let alone why they would leave humans alone for thousands of years (if you are a YEC that ignores physics, geology, chemistry, etc), or hundreds of thousands of years (if OEC).
