The age of America can be viewed in a couple of ways, depending on what aspect you are considering. If we look at the founding of the United States as a nation, we commonly refer to July 4, 1776, as the birthdate, which is when the Declaration of Independence was adopted. Therefore, as of 2023, America is 247 years old.
However, if you consider the land itself, the Americas were inhabited for thousands of years prior to European colonization. Indigenous peoples lived on the continent for at least 15,000 years, creating rich cultures and societies long before the arrival of Europeans in the late 15th century. So, in terms of human history, America has a much deeper history than just its independence.
