No, that is not how things work. You cannot bring up a theory and say because the NSA carried out a reserch on that field, then it is evidence that they had a hand in the creation of Bitcoin. Then when you receive a rebuttal for making such claims, you spin it again to say the people's reaction shows that there is truth to your theory? Don't you see how you are doing exactly what I described about conspiracy theorists? The more people try to show that your theory is not substantial, the more you say their reaction means the theory might be true. It's even crazy how you try to explain how this is different from flat earther, then go ahead to do the same thing they always do
You are correct and besides Bitcoin does not look like something the US government will create. The US government are like other government around the world that loves to control their people and Bitcoin is the opposite of that hence it can not be their creations. The US government are also among those looking for the creator of Bitcoin hence if they are the ones that created it then why are they searching and also against Bitcoin.
There would have been some bias from them since they do not like to criticize their own creations and always call themselves the best at anything they do. The US government are one of the proudest government that I know of and it shows in everything that they do hence they cannot create something that is popular like Bitcoin and then decide to stay off the media claiming their creations, that is impossible.
