What is America's oldest city?

Could you please elaborate on the question, "What is America's oldest city?" Are you referring to the city with the longest continuous history of settlement by Europeans in the United States? Or perhaps you're asking about the city that was founded first, regardless of whether it's still considered part of the United States today? Additionally, it's worth noting that the definition of "oldest" can vary depending on the criteria used, such as the date of the first permanent European settlement, the date of incorporation as a city, or the historical significance of the settlement. Could you please clarify your question to help me provide a more accurate answer?
