Faint signals from a distant galaxy offer hope for humankind

For the benefit of readers who may not know, Somtow Sucharitkul is actually the renowned musical composer, conductor, writer and polymath SP Somtow. He strikes a sombre note at the end of his eloquent letter in urging us to make a final attempt to save human civilisation, flawed though it is. Fear not, Khun Somtow: help may be on the way.
Social media, whose pronouncements are always infallible, report detecting a conversation that allegedly took place recently in a distant galaxy. I pass it on despite serious doubts about its authenticity.  Social-media freaks have imaginatively designated the speakers as God and Gabriel:
Gabriel: Sir, the humans are in trouble again.
God: Humans? Who are they?
Gabriel: Creatures you created aeons ago. In an obscure galaxy out there. On the third planet of a minor solar system.
God: Ah, yes. I remember now. Didn’t we evolve them out of some sort of mammal?
Gabriel: Yes, sir. They’re primates, sir.
God: Primates. Jesus. I should have known better. You can’t do anything with primates. Primates belong on the scrap-heap of evolution. Next time we’ll try out the insects. We’ll design an insect that’s big and warm and cuddly and super-smart. But didn’t that species – what do you call them? – extinctify themselves a long time ago?
Gabriel: Humans, sir. They’re called humans. No, they’re still hanging on.
God: Well, tell them to let go. We don’t need primates. They’re obsolete.
Gabriel: Sir, why don’t we give them another chance? Remember what you told them a long time ago? “I desire mercy, and not sacrifice.”
God: Hmmmm. Yes, I did say that, didn’t I? All right, give them a shot of evolutionary mojo. Tweak their genetic structure. Make them a kinder, gentler species.
Gabriel: Yes, sir.  Smarter, too, sir?
God: Smarter first and foremost, Gabe. Always.
So there is hope, Khun Somtow. If you believe social media.
