I dont really think so, if some government where behind the creation of Bitcoin and Cryptocurrency then they would lose all control with their citizens tax collections and unable to make revenue and even damaging their own local banks investment program and monetary system thus ruining their Economy.
You can consider the possibility that after the government created bitcoin, it lost control over it. And that is why now the government is trying to hinder the development of bitcoin, and in some cases even prohibit it. And so, as an alternative to bitcoin, the government is now working on creating a national digital currency.
