In it, it forbids murder, robbery, rape, kidnapping, lying, and so on

Which are mala en se

Things people have always regarded as wrong

So where did the Sumerians get the idea? WHY did people always regard them as wrong?

They got it from intelligence

Where did that intelligence come from?

Those thing have always been short term in their gains and far more detrimental

The intelligence came from learning

Learning how? Reading? So prior to the invention of writing, no morality could exist?

Even animals will not engage in many of those things alone

Oh yes they will

Animals rape, kill, eat each other, steal, a whole list of things

What animal only rapes?

What animals only kill with no need to eat?

Surplus killing is rare in animals

Ducks, geese, bottlenose dolphins, chimps, orangutans

Rape isnt common in animals nor is wanton murder

It bears too much risk

And therefore is wrong

Up to half of all matings of orangutans are rape

So if there's no risk, it's right?

Which is a small amount compared to the entire animal kingdom

Its only humans who have developed minds to understand vastly complex risks and benefits that true morals appeared

Risk and benefit doesn't weigh into it

There's very little risk in many immoral acts

There is very little benefit in those acts most likely

Such as lies

I can probably kill someone and take a lot of his shit and get away with it

47% chance of being convicted

But there is greater risk

That's less than half

And that also is taking into account that the vast majority of murderers are dumber than dog shit

If you lied to that same person there is 0 chance of being convicted

Of those same murderer though how many have gone to hell?

Most

The correct answer to that if I remember correctly is that only god could possibly know. Anything else is you assuming you know better than god.

Did God not say, thou shalt not murder?

How do you know that most of those people actually commited murder?

How do you know they were injustly charged?

Proof beyond a reasonable doubt, including their own confessions

It is only for god to know those things
