Aliens would be affected by sin but the salvation through Christ that the inhabitants of planet Earth benefit from would not apply to them, according to Ken Ham.
The creationist used his blog to offer his thoughts on alien life and salvation after NASA administrator Charles Bolden said last week that it was likely alien life would be discovered in the next 20 years.
"It's highly improbable in the limitless vastness of the universe that we humans stand alone," said Bolden.
Even if that turns out to be the case, the Answers in Genesis founder says the Earth was "specially created" by God and the sin committed on Earth would affect the rest of creation.
"You see, the Bible makes it clear that Adam's sin affected the whole universe," he said.
"This means that any aliens would also be affected by Adam's sin, but because they are not Adam's descendants, they can't have salvation."
In his view, Christ's work of salvation would only apply to humans as the descendents of Adam.
"Jesus did not become the 'GodKlingon' or the 'God Martian'!" he wrote. "Only descendents of Adam can be saved. God's Son remains the 'Godman' as our Savior. In fact, the Bible makes it clear that we see the Father through the Son (and we see the Son through His Word). To suggest that aliens could respond to the Gospel is just totally wrong."
NASA may be committed to hunting for extraterrestrial life, but Ham thinks they should stop right here. The search to find aliens, he suggests, is itself a product of man's sinful nature "driven by man's rebellion against God in a desperate attempt to supposedly prove evolution!"
