How do you know that they are amoral?
Because they don't enter into the realm of moral consideration. Which is to say, they don't necessarily concern harm and wellbeing.
Since you dont believe in objective morality
I do believe in objective morality. Just not what you consider to be objective morality, which isn't objective at all.
But you dont even know what is good or bad for such beings since you dont believe in objective morality or objective value.
I do know what is 'good' or 'bad' for such beings. 'Good' is that which increases wellbeing, reduces harm, or does both. 'Bad' is that which reduces wellbeing, increases harm, or does both.
As to whether that is
valued, that is necessarily subjective, and invoking Yahweh will not magically make it objective. Ever. 'Objective value' is an oxymoron.
Also what is your definition of sentient?
As it pertains to this discussion - capable of experiencing harm or wellbeing.
I am not denying that engaging in social activity is good for people, but do you have any actual studies that show that non-churchgoers are just as law abiding than church goers?
Here's one, but you have to pay for it,
https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1751-9020.2009.00247.x
But I encourage anyone reading along to do their own research. Just for example, try googling 'US states by crime rate' and 'least religious US states', and notice a blatant pattern emerge.
Because there have been multiple studies that show churchgoers are more law abiding.
I am not aware of any that demonstrate an
exclusive benefit of church attendance in this regard, so you will have to provide them if you want to make your point.
But there is scientific evidence that the bible has a divine origin.
I've seen what you consider to be 'evidence' on this point. I am unimpressed, to put it politely.
The value of humans is objective, because our value is based on our being created in the image of the creator.
No, being 'created' is not a means of determining objectivity. You will not ever get around the fact that value is necessarily subjective, no matter how many theological buzzwords you invoke.
Hitler and Stalin thought that they were furthering the well being of their people by slaughtering those they thought were enemies of their people.
They thought that, and they were wrong. People being wrong in their assessment does not change the fact that harm and wellbeing are objectively quantifiable. People are wrong about all sorts of things that are objectively quantifiable, all the time.
Utterly irrelevant to morality.
Even assuming he exists, there is no means of gleaning if he has a moral code.
Even assuming he exists, and that he has a moral code, there is no means of gleaning what that moral code is.
Even assuming he exists, and that he has a moral code, and that we have a means of gleaning what that moral code is, there is no reason why that code should necessarily be adopted.
But how do you determine what is harm and what is well being? Many people consider some types of suffering good, it helped strengthen their character or helped them get closer to their god or many other things.
That is a good question. Some harm may be good for you, in the long run. Chemotherapy, for example, makes people terribly nauseous and uncomfortable, but it can treat cancer, which is worse than being nauseous.
Other examples are more esoteric. Some people choose to view the death of a loved one as a 'test' of their own emotional fortitude, and ultimately good for them, which is a coping mechanism some people use in dealing with loss. Other people see it differently.
And that's ok. The fact that there are these more ambiguous moral areas, does not mean we need to throw up our hands and say 'well, I guess we can't tell if breathing is good for us, or drinking motor oil is harmful'. We can still tell black from white, despite the fact that grey exists.
