This is why concepts such as right, wrong, good and bad are relative, with no omnipotent deity to give them objectivity.
Objectivity? And you suggest that some deity provides objectivity?
Which one? There are some 4,200 extant world religions, and an untold number of extinct ones.
And how does one decide among those often conflicting religions, to determine which (if any) is correct? Evidence? The scientific method? Ouija board? Voices in one's head?
Later in your post, you wrote:
500 years ago it was acceptable to throw your children to the alligators, for purposes of worship, something you would abhor.
A couple of thousand years before that it apparently was acceptable to take your child and cut his gizzard out because some deity commanded it. Is that right, wrong, good, or bad?
I'll tell you: its wrong and bad. Why? Because it is anti-life, anti-survival, and anti-rational.
And I don't care what your, or any other, idols or demons say (or, more precisely, what some person
claimed that those idols or demons said).
If you disagree with this, as I suspect you might, provide
evidence to the contrary. And please, don't bother to provide as evidence what some person claimed the voices in his head told him.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
