African countries has depending on others international countries in so many things such as motors manufactures, and so many technologies, there have only one country which using their own technologies which also are carried by white mans from that country, that country is South Africa.
The reason that's makes African countries to not be discovering their own technologies is due to lack of creativity which from when children's are in schools, they are just be forcing to learn things that already discovered by other countries instead of learning our things.
So that's why for this reason African countries having so many worthiest resources but they don't know how to use them, and that's lead to give those resources to international countries, and then those countries use those resourses to make products and returning to Africa again.
