What is the date afica came to existence?

Africa, as a continent, has existed for millions of years, with its geological formation dating back to the Precambrian era. However, the modern concept of Africa as a defined geographical and cultural entity emerged over time, particularly during the colonial period in the late 19th and early 20th centuries. The recognition of Africa as a distinct continent has evolved, but it has always been home to diverse human civilizations for thousands of years. Thus, there isn't a specific date for its "existence," as it has been part of Earth's history long before recorded time.
