Scientists say they have found an extraterrestrial cemetery in central Africa that is at least 500 years old!

"There must be 200 bodies buried there and not a single one of them is human," Dr. Hugo Childs, the Swiss anthropologist, told reporters in Kigali, Rwanda.

"They are in amazing state of preservation to be so old," he added. "Soil and tissue samples indicate the bodies have been in the ground since the 1400s. We're now trying to figure out where they came from - and what killed them."

Dr. Childs and his colleagues reportedly discovered the alien graveyard on a routine survey of the Rwandan jungle.

They originally thought they had stumbled on the remains of a centuries-old village. But excavation reportedly revealed nothing but alien bodies - stacked in fives in a jungle clearing.

"The creatures themselves were much taller and skinnier than humans," said the expert.

"They stood about 7 feet tall and they were not any bigger around than small sapling trees.

"Their heads were larger than the average man's and they had no mouth, nose or eyes to speak of.

"I assume that they communicated with one another telepathically and moved around like bats with some kind of biological radar."

Without further study there is no way to tell for sure what killed the extraterrestrials.

But Dr. Childs speculated that the 200 aliens were part of a single landing party that encountered a deadly virus. Because they would have had no immunity to Earth disease, he added, something as simple as the flu could have wiped out the entire party.

"Some of them must have survived because there is no evidence of a spaceship to be found," said Dr. Childs. "Of course, as our excavation effort continues, there's no telling what we may run across."

Dr. Childs would not take reporters to the site, for fear of the bodies being disturbed. However, he promised to reveal the location once the excavation was complete. "It will change the world," Dr. Childs said.
