they mean that all life started in africa due to fossil findings which are supposedly the oldest on the earth found today..
then conclude that adam and eve had to have started out in africa, since the bones theyve found there are the oldest..lol..
from africa, they populated the world by migrating to other places, crossing land bridges and so forth..
these theories are based on modern science and peoples distorted beliefs on the bible, which are both "FALLIBLE".
Personally i don't believe in the AFRICA theory.
i do believe all humans descended from adam and eve though. BUT - the location of the "GARDEN OF EDEN" WAS NEVER stated in the bible, therefore it could have been almost ANYWHERE on the earth, and from it, a migration to other places on the earth took place..
Aside from the adam and eve part, these theories aren't specifically a Christian thing, trust me theres a horde of people both religous AND non-religous out there that believe in all kinds of scientific hogwash..
the black RASTA people from jamaica believe that Haile Selassie, the former Emperor of Ethiopia, is God incarnate, whom they call Jah. Where they came up with that non-sense? who knows.. but if any Native american who gives them credit because they are black and not christians or something like that then SHAME SHAME SHAME ON YALLZZ.. LOL..
blacks in general, and many black "created religions" such as "nation of gods and earth" and "5 percenters", Believe in the theory of all life starting in africa and that they are everyones ancestors, haven't you noticed that yet?!? 5 percenters also believe that the BLACK man were the original gods on the earth.. they go CRAZYYYY for the notion! lmaooo!! you try telling one of them they are wrong, and they automatically call you a racist LOL..
as for the science and fossils part, its all GUESSWORK when they find bones and put a date on it.. there are MANY places in the world that haven't been properly excavated yet, they still haven't even found Ghenghis khans burial spot!!
