Christian creationist Ken Ham, who heads the Ark Encounter in Williamstown, Kentucky, leaked pictures of a new exhibit on Feb. 16 that appear to show a coliseum fight between giants, dinosaurs and humans.
Ham tweeted the pictures with this caption: "Exquisite design by [ArkEncounter] artists for new Diorama depicting wicked population in the pre-Flood world to be installed."
The Huffington Post notes that Ham believes the earth is 6,000 years old, humans co-existed with dinosaurs, and Noah included dinosaurs on his Biblical ark some 4,300 years ago.
The news site notes that dinosaurs died out about 65 million years ago, and there is a lack of evidence for the existence of giants.
The Smithsonian Institute's web site says that paleoanthropologists believe modern humans evolved in Africa about 200,000 years ago.
The science site says there is a scarce supply of fossils for these early humans because it's hard to recognize authentic modern humans due to modern and primitive traits in the early human fossil records.
Dr. Andrew A. Snelling, who is a geologist, wrote on Ham's Answers In Genesis website how secular science is faulty when it comes to dating rocks with radioactive methods and produces error-filled estimates of the earth being billions of years old.
Snelling noted that some daughter atoms (atoms left after decay) are inherited by rocks that were not formed by radioactive decay by those same atoms.
Snelling also argued that parent and daughter atoms often contaminate the wrong rocks, and the parent and daughter atoms can be removed from the right rocks by way of geologic processes.
According to Snelling, another problem is that nuclear decay rates, also known as "clocks," have been reported as inaccurate for rocks of known ages.
In his article, Snelling asked, "[I]f these 'clocks' don't work on rocks of known ages, how can they be trusted on rocks of unknown ages?"
There was a study in 2010 by Stanford and Purdue University researchers that found solar flares from the sun may affect the radioactive decay rate of some elements; the study did not question the age of the earth.
