No, I don't agree. In 1899, late in the year, the US Patent Office had an article published in the NY Times that the patent Office would close at the end of the year because everything that could be invented had already been invented. It was a joke, but a lot of people believed it, just as they believed, contrary to being told on the hour that Orson Welles' "War of the Worlds" radio broadcast in 1938 was an actual news broadcast from New Jersey that we were, in fact, being attacked by Mars. And that is matched by many opinions expressed on History Channel's "Ancient Aliens" that our ancient ancestors would still be in caves today had we not the education of aliens to create our civilization. The same show claimed our DNA is derived from 3 basic amino acids. It happens to be 4, but, it was on TV, so it must be believed.
Mark Twain once said, "It ain't what you don't know that gets you in to trouble. It's what you know for sure that just ain't so."
The same kind of illogical belief as your assumption drives the absurd belief that the human mind is not creative nor inventive. Bullshyte, even if you believe those ancient aliens have names like Elohim, Jehovah, Jesus, or Allah, let alone Zeus or Mars.
