Creationist Ken Ham is very concerned that Disney's new animated film called "The Good Dinosaur" would be out to promote the theory of evolution among children. Based on what he saw in the full-length trailer, he says his theories have been confirmed.

"This new movie claims to show what might have happened if the supposed asteroid impact that killed the dinosaurs in the most popular evolutionary dinosaur extinction theory had missed Earth," he writes in his Answers in Genesis blog.

In the trailer, an Apatosaurus meets a young boy who isn't quite fully developed yet, since "he acts more like an animal than a human and appears not to be very intelligent," according to Ham.

The human would growl, howl, and even bite, but never speak.

"It seems to me that the intended impression is that this young boy has not quite yet evolved to be fully human," Ham observes.

In an earlier blog post, Ham says Christians should use the negative aspect of the movie to promote the positive effects of Christianity.

"Now, despite the evolutionary presuppositions behind 'The Good Dinosaur' (and the evolutionary content that will likely be part of the film), this movie can also be used as a touch point with the culture to start gospel-centred conversations," he said. "Just like in Acts 17 when the Apostle Paul took a pagan altar and used it as a way to proclaim Christ, so can we take a movie like 'The Good Dinosaur' and use it to point to God's Word and the gospel."

Ham says people can talk with their family and friends about how dinosaurs and man really did live together in the past, and how dinosaurs went extinct. Afterwards, people can discuss the history in God's Word that can be trusted.
