A creationist has rejected the age of a primitive human jawbone found in Africa believed to be 2.8 million years old.
Experts say the fossil, uncovered in the Ethiopian Rift Valley, appears to be the oldest known member of the human family.
Dr Tas Walker, a creationist and geologist with Creation Ministries International said he didn't believe the dates.
He believes the flood of Noah wiped out dinosaurs.
"There are all sorts of dating methods based on assumptions about the past," he said.
"I don't believe the dates, by any means. The only way to reliably know the age of something is by eyewitness reports and the bible gives us an eyewitness report."
Dr Walker acknowleged the discovery of the single row of teeth, known as Ledi-Gerau, but said the fossil's age was not set in stone.
"The evolution interpretation is based on a belief system that evolution happened," he said.
