As someone who writes a lot, you need to be less literal. Write more poetry.
The thread topic is god working giant miracles to prove itself. Anecdotes about subculture use of vocabulary is irrelevant.
Someone else (more than one 'someone else') brought up Babel. That means I'm on-topic, even if it's in response to someone else's example.
As for my writing...
Spoiler writing discussion rebutting the above re: "less literal" and "write more poetry" :
"Less literal"?
I write fanfiction. Specifically fanfiction based on games, most of which are fantasy-based. Even the one about the fictitious national park in Washington has a fantasy element, 'cuz how else to explain how part of Jasper National Park got tossed into Pinecreek Hills National Park? (okay, the game devs are just a wee bit geography-challenged, didn't want to spend time creating yet another scene within this park, used an image of one of our parks, and probably didn't think anyone would notice)
I have written poetry. I can appreciate a good metaphor. There are two main characters in King's Heir who write music and poems. Since the people who created the game this is based on didn't put this into their version and they didn't even have one of these characters (she's one of my creations), it means that I have to create these songs and poems myself. I've actually written original songs. That's part of what you have to learn in order to pass the Western Board of Music theory exams.
I've done a lot of worldbuilding for the setting of the story based on King's Heir. It's set in the early 11th century, and I decided not to get into real-history politics and religion. I decided that yes, the characters will mostly be people of faith, but I don't want to mess it up with real-history stuff. That's more research than I'm willing to put in, and it would result in characters who think and behave differently than the characters I fell in love with, and I wouldn't like them anymore. Besides, the game creators introduced magic in the last chapter of the main game, and I had to decide how to handle it when turning this into prose - ignore it, or work with it. I chose to work with it, though it felt strange at first. There's no explanation of how the magic works in the game, so that's something I've been having fun with in the writing, letting the characters figure it out as I do. The easiest and laziest way, of course, would be to say "Goddidit." But the Judeo-Christian god isn't in this story.
I made up a religion for them to follow, and even though their neighboring kingdom has a different set of beliefs, there's not much strife about it. They're certainly not going to get into a religious war, or use religion as the excuse for a war. If they go to war, it will be for some other, honestly-stated reason.
To sum up, I can create a fictional society of medieval-era people without the religious baggage we've had in real history. Yes, they've got their own problems, but that's prequel material that I won't be touching for a long time yet.
Oh, and the afterlife? It's real in this story. If the game devs can create a magic crown that kills anyone who tries to put it on and is not of the proper lineage to be king/queen, I can create a real afterlife for the dead characters and have people react in a variety of ways when one character tells others that he can speak to the dead.

The rest of these are out of order, but whatever.
I did say God would resemble the old testament Gid along with the ability to enforce their claims.
This means angels of death, pillars of salt and destruction of cities and nations if need be.
We already have these.
So why is it appearing in the clouds issuing demands in a booming voice? Rather destroys the importance of faith when its being all manifest right there.
Thunder is a "booming voice". It's not intentionally telling people what to do, but getting indoors is the only smart thing unless you want to risk a lightning strike.
Well as I said that power is consistent with the various holy books and can't be explained via science. Essentially real magic.
There are many things that can't yet be explained by science. YET. It may take a very long time in some cases, but I think humans are up for the challenge. We've come a long way so far.
Well in this case God can directly cause miracles or destruction.
I can cause miracles or destruction whenever I play Sim City or Civ. I don't demand that the fictitious people in the game worship me. In fact, my games are short on places of worship. But they do make it to Alpha Centauri ahead of schedule, with 100% literacy and plenty of Future Tech.
It's good that Zard hadn't said "867-5309 years ago."
I do believe in God, the Christian God. So the difficulty for me in the scenario you sketch wouldn't be the existence of God, but the fact that he was backtracking in terms of his message and his method of communication.
Dunno if anyone ever converted after attending a performance of Jesus Christ Superstar, but it was a fun show to work on. The only person among the cast and crew to have a bad mood during that whole time was the stage manager, but she was always a grouch anyway. The rest of us were high on a good time. That was the year I read the New Testament, in order to understand some of the songs.
We though what Troy doesn't exist. 3 year ago we didn't know, what Africans also have parts of Neanderthals
We still don't know origin (as I know) of Indo-European group... Actually, we even don't know all animals living deep in oceans.
If we don't know - it doesn't mean that it doesn't exist
Yes, I'm aware of these things, thank you.
You missed my point, which was about the story of the Tower of Babel. You're not going to convince me that the reason people speak different languages now is because some people got together thousands of years ago and built a tower that offended their god. And since you're not going to convince me of that, I'm equally not inclined to take seriously the idea that some deity can suddenly appear and make all those extra languages go away so we all speak the same one.
If it were to happen, cue the rage from some people if theirs isn't the language chosen to be "universal". We've already got that going in Canada, over the French/English thing, and because the Prime Minister appointed a new Governor-General who doesn't speak one of our official languages. Sorry, Mary Simon, but Inuktitut isn't a federal official language.
