An Australian man claims that he has proof of the authenticity of Bible's story, which claims humans and pre-historic giant creatures co-existed thousands of years back.

Ken Ham, the founder of the Creation Museum in the US, has unveiled the fossil skeleton of a nine-metre-long Allosaurus.

The skeleton remains of the Allosaurus bears resemblance with the Tyrannosaurus Rex and is the centre piece of the Kentucky museum.

Ham is currently building an $80 million Noah's ark in America and has defied his critics by displaying the huge Allosaurus, which he named 'Ebenezer.'

During a heated TV debate with science educator Bill Nye in February, Ham said, "The new exhibit will help us defend the book of Genesis and expose the scientific problems with evolution.

"Evolutionists use dinosaurs to reach children more than anything to promote their worldview," Australian born Ham added. "Our museum uses dinosaurs to help tell their true history according to the Bible."

"If there was a big flood on the earth, you would expect drowning animals to swim up to a higher level," Nye replied. "Not any one of them did, not a single one."

The owner of the Creation Museum has revealed that the fossil remains of the Allosaurus were discovered in Colorado over a decade ago.

The museum claims that according to the Bible, dinosaurs died in a worldwide flood about 4,300 years ago while scientists believe that dinosaurs existed on earth until the mass extinction more than 60 million years ago, Australian website reported.

Meanwhile, Daniel Phelps, president of the Kentucky Paleontological Society, has criticised the ministry's claim and issued a press release saying, that "the Creation Museum has decided, without doing research, that the dinosaur fossil is evidence of Noah's flood."
