Can you give me irrefutable evidence for moral right and wrong?

There are different kinds of evidence. Scientific evidence is what you can see under a microscope but that is limited. We are children of God and we are made in God's image. That is what most people believe. If I believe something and base my whole life on it, that may not be enough 'evidence' for you. You say 'irrefutable evidence' but all evidence can be refuted. People can disagree. If you do not believe in God, then you believe people are just intelligent animals, then there would be no reason to believe anything is moral. But many things are preferable to other things. It is better to save a person from drowning than to kill someone. But the issue is not whether there is evidence that is irrefutable or not. There is little that is irrefutable despite what you learn in high school. We do not understand gravity or light of matter of the electron. We know some things but we have more questions than answers. There is not really irrefutable evidence for anything. But some things are more likely than others. There are very few simple answers. You are asking for a scientific answer to a moral question. The two are not the same.

Morality is based upon society's views. That's why things like homosexuality is downplayed in some areas. Even the religious will change what they see as moral. Example, once upon a time, it was sinful to shop on Sunday. My home state of Missouri actually banned many stores from opening (groceries and medications were about the only exceptions) because it was sinful. Even the view of Evangelicals towards Mormons changed when Mitt Romney ran for president four years ago, and some are trying to justify the immorality of Donald Trump as "acceptable" because of the unacceptability of Hillary Clinton.

In other words, morals can change because of society, and it's not just restricted to the "secular".

Research shows that the reason humans struggle with emotion to find equitable solutions is pinpointed the region of the brain called the insular cortex, or insula, which is also the seat of emotional reactions.

The fact that the brain has such a robust response to unfairness shows that sensing unfairness is a basic evolved capacity.

The emotional response to unfairness pushes people from extreme inequity and drives them to be fair. This observation shows our basic impulse to be fair isn't a complicated thing that we learn.

It therefore fully illustrates that all humans have morals controlled by the brain and that Christians are entirely wrong to try and claim morals as their own!!!!

But Christians found a way round it!

Government statistics show that Christians are vastly over represented in prisons for sexual, violent and fraudulent crime whilst year on year government figures show atheists make up only 2% of the prison population!

The Catholic Church is paying millions in compensation for the sex/paedophile crimes of their priests alone!

Christians are vastly over represented in the divorce courts!

Christians invented the concept of sin and then the idea that you could sin, ask forgiveness, get pardoned and start with a clean sheet!

So no surprise that they are so expert at it is it‽

A Christian is a man that feels repentance on Sunday for what he did on Saturday and is going to do on Monday. - Thomas Russell Ybarra

We base on morals mainly around LIFE. Life and anything which benefits life we see as good. Anything which damages or destroys Life we name bad/evil.

We know that there is a limited path that one must take to follow a path of constructive life. We understand that the nature of life has a structure. This structure of life is by our definition good and that which destroys it is bad.

However, I personally don't believe evil exists in nature or in an objective sense. The closest and most real evil can get is by the intentions of men. In nature, we see that things which damage life also can serve to make it stronger. So there is no objective Wrong and it is purely subjective to the interpreter.

If it's wrong for people to die, god really screwed up, because every living thing will die. The idea that it's wrong to kill other sentient creatures DOES exist only in our minds--it's based on empathy. It's wrong to kill a dog but acceptable to kill a roach, not because the roach isn't alive but because the dog has some awareness of what's going on.

No

Morality is a set of rules generated by a society to enable it to function. They change when the needs of a society changes. If you read through history, you will see this in action.

You can't unless you recognize the reality of God's Law.

Thats easy. Anything negative is wrong. Positive solutions are always right.

if the general beliefs/practices of a given society prohibit something... it is a moral wrong... every society makes rules that the members of the society are to follow... those are their "morals"
