Nope, Chris, that's not where the Amazing superlative originated.
In 1960 I was ten years old, and DC pretty much owned the super-hero business. Marvel produced monster comics and only a limited number of those. Then came The Fantastic Four (I bought it for ten cents), quickly followed by The Incredible Hulk (didn't buy that one), the first two new comics in a long time. And the last. They were the last new titles for a while because Marvel was contractually limited to eight comics a month by their distributor - which, uh, happened to be DC comics.
All of the new super-heroes that appeared when I was twelve years old - Thor, Iron Man, Ant Man and Wasp, Dr. Strange, Captain America, and of course, Spider-Man - all first appeared in the monster comics already being put out by Marvel. My allowance was stretched pretty thin that year.
Oh, and the name of the monster comic where Spidey first appeared was …
