Well, look at how, for the United States, the Declaration of Independence refers to a God numerous times. And then, the Constitution has no references to a God.
Let's take a step back and temporarily suspend the notion of the United States and every other country for a minute.
They actually found a relic, over 10,000 years old, that shows how our species has been using religion for these purposes once our brains evolved to what they did.
I'm pretty sure religion, as we know it is even older than that. Long before our predecessors started the migration out of Africa, religion and the use of religion to manipulate the tribe was a thing. Religion, and the fear that the gods would seek revenge if you stepped outside the shaman's divine teaching , followed naturally. This is not surprising however. Primitive man looked upon the flowing waters and came to the natural conclusion that, since it is not a man that makes the river flow, it must be the work of some higher power. The shaman just tapped into that and declared themselves a prophet of that higher power. This then created a counter to the alpha-male and, over time, was used to usurp the power of the alpha-male, for good or for bad.
And so the gods of the river, the gods of the sky, the gods of the moon, the gods of the trees, etc. were given names and statues of them were conceived and constructed so that the populace had a physical object they could bow before. Because there were now physical manifestations of the gods, even the alpha-male (a.k.a. Pharaoh, Caesar, big-boss) also had to bow to the statues lest he anger the gods and upset the populace.
Lo and behold, while all this bowing and scraping was going on, along comes some dudes saying "Hey guys, there is only one god". Resultant effect = organised religion. Yet still you had the alpha-male except the title has changed. It is now no longer Pharaoh or Caesar, it is King or Emperor. But still the quest for more power (invasion of neighboring territories and suppressing the conquered), greed (more land with tax-paying peasants to farm the land = greater wealth), politics (if my daughter marries the king's son I will be a member of the court) and religion (if the King pisses off god he's not gonna be popular) hold fast.
Not much has changed. Well changed a little perhaps. Now we call the alpha-male 'president' or 'prime-minister'. But the alpha-male's actions still require sanctioning by greed (corporations), power (lobby groups) and religion.
I fear that while self-interest and self-benefit dictate the rules and thinking of society, the aforementioned constructs cannot be rebooted. Or, they could, but it would require the cooperation of the global society, not just a Black Lives Matter movement, or a Greenpeace movement or an independent Hong Kong movement or an anti-apartheid movement. It has to be a collective effort, a collective will to stop thinking about ourselves and start thinking about the future's of our children and their children as a whole.
Sadly however, the socio-polito-economical construct that we and our recent ancestors have been born into dictates we have to act for our self-interest. We have bills to pay and mouths to feed.
As long as we continue under the yoke of the current socio-polito-economical construct, our children, and their children, will continue the trend and these circumstances and debates will reappear again, and again, and again.
