School in rural area spots unknown craft landed in valley below with black humanoids patroling outside.I was formally a student at a primary school based about 25km out of Harare(Capital of Zimbabwe). It was at recess that a crowd of pupils began assembling at the base of the playing feild. I personbally only saw what looked like a perfectly shaped oval granite rock about 500 metres away in the virgin African bush down in the small vally below the school. It seemed to be glitering. Other students calimed that they could see black men with fur on their backs.I however did not see such creatures.An emergency assembly was called to calm down all the students. After we returned to break the rock as I ,thought it was, had vanished.A trip down to the site revealed the a colony of army ants had completly been killed.((NUFORC
