They may only be weeks away from their wedding, but Jessa Duggar and Ben Seewald didn't look the least bit stressed as they joined the giant Duggar clan in a visit to the Creation Museum. 

The doting pair were joined by Jessa's parents Jim Bob and Michelle, and 13 of the Duggar children at the museum in Petersburg, Kentucky, on Tuesday.  

The 19 Kids and Counting stars were more than happy to pose for a picture with the museum's founder, the creationist Ken Ham.  

Ham was equally delighted with their visit, writing on his blog: "Please pray for the Duggars and the incredible public ministry they have as they have witnessed to millions of people.  Thanks for stopping by and thanks for praying." 

The visit must have been a nice distraction from all the wedding preparations for Jessa and Ben, as the pair enjoy their last few weeks before becoming husband and wife on November 1.

Following their visit, Jessa wrote an explanation about the creationist viewpoint of the Earth's history on her Instagram.  

"If there really was a worldwide flood (as the Bible speaks of), what would the evidence be? Billions of dead things buried in rock layers, laid down by water, all over the earth," she wrote.

"And that's exactly what we find. Billions of dead things buried in rock layers, laid down by water, all over the earth.

"An Evolutionist and a Creationist will look at the same thing, but come to different conclusions because of their different starting points."

She also shared a sweet picture of her sister Jinger at the museum.
