This carefully phrased statement will appeal to both the democrats and the republicans - as people tend to hear what they want to hear. Many will probably interpret this to mean Scaramucci believes in the Young Earth Hypothesis, and they will support him even more. If ever confronted by non believers, he can quickly turn around and claim that he referred to "5500 years of human history and that he never implied anything about his beliefs in the planet being only 5500 years old.

Wtf. You either believe in something and you stand by it or you don't. Sitting on the fence when you are the national advisor is kind of counterproductive. Playing with words to be "safe" from hostile feedback is childish.
