Ken Ham is ready to do battle once again with an unlikely foe, televangelist Pat Robertson, over their differing views on the age of the earth.

Responding to Robertson’s recent remarks that “you have to be deaf, dumb and blind to think that this Earth that we live in only has 6,000 years of existence,” Ham fired back on his Facebook page yesterday.

Ham, whose group Answers in Genesis runs the Creation Museum, said that Robertson’s comments were “beyond ignorant” and incorporated “pagan ideas,” arguing that his attack on “the authority of the Word” amounts to an attack on Jesus Christ.
