In central Africa, near the city of Kigali, the scientists found burial, dating back about 500 years. Examining the remains, anthropologists have come to the conclusion that the graves belong to creatures, not like a man.
Some of the experts tend to believe that these graves could belong to aliens, but the cause of death can not call nobody.
At 40 "mass graves" there were the remains of about 200 bodies. All unusual creatures had a high growth (under 2 meters), and a disproportionately large head without eyes, mouth and nose.
Experts have suggested that the dead could be part of Space Marines destroyed by any earthly virus.
