Well despite these quotes I do think that this is nor an exceptional thing nor impossible since it was long speculated that bitcoins was indeed made by a team and a group of people and it was not something that could have been done by a single person. The programming and the introduction it would have taken years for sure. Plus I do not think that it is wrong..... The inventor is always the inventor and he for sure would employee people to help him out with it. That's how a company works for real.
At the same time I do think people already know that the idea of bitcoins did not originate within seconds , rather it was a long process.
For example a quote from wiki :
Cryptographer David Chaum first proposed a blockchain-like protocol in his 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups
Which does mean that Mr. Satoshi would have read the guy's article and worked and created the idea and then assembled the team to make this real !! That's just how inventions are, it's always a group effort.
