In Rubingo there was land slides and killed all old people and left the young so the children are confused about how to find there origin as as history man help the children

As a history man, I'd advise the children of Rubingo to look for clues in their environment and culture to find their origin. They can investigate archaeological sites for old tools, pottery, or building remains that tell about past inhabitants. They should also try to recall any stories, songs, or traditions that might have survived, as these often carry historical information. Finally, connecting with neighboring communities can often reveal shared histories and origins, as societies rarely exist in complete isolation.
