I can understand Africans desire to leave, however, they have never envisioned anything like travel on the oceans or shoe laces. Lets try a peoples like the Phoenicians or Mesopotamians. Africans missed the bronze age, iron age and industrial revolution for a reason!
'First Americans Were Australians.'
You might be a little hard on the Africans. First, you can’t separate the Egyptian Civilization from Africa, particularly because it seems the Egyptians came in large measure from the Sahara as it dried out. Also, you have the Nubian, Ethiopian, Kushan and West African Cultures. The Nok, Bantu, Ghanan and Benin cultures in West Africa began about 900 BC growing from agricultural settlements. The Sahara was their “ocean”. The impact of the spread of Islam which leveled cultures out to a Muslim pattern certainly had its impact in Africa and in the trade routes moving gold, copper, ivory, etc. North across the Sahara to the Mediterranean. European colonialism was a further blow to African civilizations already savaged by Islam and an expanded slave trade.
