In 2014, did nearly half of all Americans believe in Creationism? A 2014 poll by Gallup seems to say that in the U.S., 42% believe Creationist view of human origins. Is this really true? Are any of the claims from this study dubious?

The figures are roughly confirmed by a different 2014 survey by Pew Research (Sample size = 35,071) :

33% believe "Humans and other living things have evolved due to natural processes such as natural selection"

25% believe "A supreme being guided the evolution of living things for the purpose of creating humans and other life in the form it exists today"

34% believe "Humans and other living things have existed in their present form since the beginning of time"

4% believe "Humans and other living things have evolved over time" but don't know or refused answer whether this involved a supreme being

4% simply didn't know or refused to answer

The sample size of the Pew survey is 35 times larger than the Gallup survey.
