Which country made Ethereum?

I'm quite curious about the origin of Ethereum. Could you please enlighten me as to which country was responsible for its creation? I've heard various rumors and speculation, but I'd like to get a clear and concise answer. Was it a developed nation with a strong technological background, or perhaps a more under-the-radar locale? I'm fascinated by the technology behind Ethereum and its impact on the cryptocurrency landscape, so any information you can provide would be greatly appreciated.
