The search for extraterrestrial intelligence is a huge waste of time, according to creationist Ken Ham.

Ham, who runs creationist attractions in Kentucky including a supposed replica of Noah’s Ark complete with replica dinosaurs, claims that aliens can’t possibly be intelligent... because they can’t possibly exist.

Writing on his “Answers in Genesis” blog, Ham attempted to respond to Scottish astronomer Duncan Forgan, who has been running computer simulations about the possibility of alien civilizations.

Forgan lamented in a Fox News interview the difficulty of testing some theories in his simulation because of the lack of data on alien behavior.

Ham predicted that problem would never be solved.

While there is no evidence yet for extraterrestrial life, a number of NASA scientists have said they expect to find it in the coming decades.

“I think in the next 20 years we will find out we are not alone in the universe,” NASA astronomer Kevin Hand said in a 2014 discussion.

Hand’s boss agreed.

“It’s highly improbable in the limitless vastness of the universe that we humans stand alone,” NASA Administrator Charles Bolden said.

However, Ham wrote in his Sunday blog post that people searching for alien life are really looking for replacements for God.

“Only a life pursuing our Creator will give us the answers and purpose we seek,” he wrote.

Ham, who once debated “Science Guy” Bill Nye, wrote in 2014 that aliens ― if they did exist ― would be beyond salvation because they are not descendants of the biblical figure Adam.

“Jesus did not become the ‘GodKlingon’ or the ‘GodMartian’!” he wrote at the time. “Only descendants of Adam can be saved. God’s Son remains the ‘Godman’ as our Savior.”
