I didn't specify, but the two most discussed here, Hemen-hotep and the Iram thing, both show
after the fact origins.
Meh.
Clarke wrote as he thought and lived, so:

And Asimov,

(I didn't try very hard.)
No you didn't try very hard. I'm not even sure that you bothered to read what it is that you were posting, before posting it.
In 1974 (about 30 years after the
first computer) Arthur C. Clarke predicted that we would one day have online banking, and online shopping. OK, maybe you are unaware of the fact that the development of the Internet can be traced back to 1958. This is an example of Post-hoc analysis/prediction, where someone looks at how things are developing and then makes an educated guess as to how they will turn out. Quite unimpressive, unless you are an atheist.
And are you truly impressed by the statements which were made by Sci-fi author Isaac Asimov in 1964? Where he managed for 3/12 of his guesses about the future to be correct.
1. The human race would be incurably bored?
2. Gadgets would be powered by "long-lived batteries running on isotopes."
3. Fission-power plants that would energize most of the world
4. "power stations in space, collecting sunlight by means of huge parabolic focusing devices and radiating the energy thus collected to earth."
5. "Jets of compressed air will also lift land vehicles off the highways, which, among other things, will minimize paving problems...cars will be capable of crossing water on their jets, though local ordinances will discourage the practice."
6. There would be robots
7. "compressed air tubes will carry goods and materials over local stretches, and the switching devices that will place specific shipments in specific destinations will be one of the city's marvels."
8. Humans would have colonized the moon
9. "cities in the deep sea with bathyscaphe liners."
10. The area from Boston to Washington, D.C. would become one big city
11. Life expectancy would hit 85 years old in some parts of the world
12. "the world of A.D. 2014 will have few routine jobs that cannot be done better by some machine than by any human being. Mankind will therefore have become largely a race of machine tenders."
Then by the criteria which you have just established the following predictions which were made by Muhammad (saw) would also be considered quite spectacular (if not miraculous

), considering the length of time before their actual occurrence, and the fact that many are much more specific.
