Sure, you have said that we have things which tell us right from wrong. You have scientifically proved this. The Bible also said we have these things, and the writers did not have to go to behavioral science class to find out.
The old testament is replete with examples and statements that demonstrate the ethic of reciprocity.
However note the OT scoped this principle to only include those who could also scratch your back (ie thy people)
Leviticus 19:18 writes:
Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbor as thyself: I am the LORD.
This is the same "ethic" recognized my chimpanzee groups.
Not very inspiring or out of context with the beginnings of other cultures.
Also every major religion has this feature embedded into it's fabric. The bible is not unique.
Another note is the earliest written example of the rudiments of this ethic predates the biblical reference by centuries. Look up Egyptian "The Tale of the Eloquent Peasant" (over 4k years old) which is a bit hard reading but worth the effort.
