(CNN) - Forty-six percent of Americans believe that God created humans in their present form at one point within the past 10,000 years, according to a survey released by Gallup on Friday.

That number has remained unchanged for the past 30 years, since 1982, when Gallup first asked the question on creationism versus evolution. Thirty years ago, 44% of the people who responded said they believed that God created humans as we know them today - only a 2-point difference from 2012.

"Despite the many changes that have taken place in American society and culture over the past 30 years, including new discoveries in biological and social science, there has been virtually no sustained change in Americans' views of the origin of the human species since 1982," wrote Gallup's Frank Newport. "All in all, there is no evidence in this trend of a substantial movement toward a secular viewpoint on human origins."

The second most common view is that humans evolved with God's guidance - a view held by 32% of respondents. The view that humans evolved with no guidance from God was held by 15% of respondents.

Not surprisingly, more religious Americans are more likely to be creationists.

Nearly 70% of respondents who attend church every week said that God created humans in their present form, compared with 25% of people who seldom or never attend church.

Among the seldom church-goers, 38% believe that humans evolved with no guidance from God.

The numbers also showed a tendency to follow party lines, with nearly 60% of Republicans identifying as creationists, while 41% of Democrats hold the same beliefs.

Republicans also seem to be more black-and-white about their beliefs, with only 5% responding that humans evolved with some help from God. That number is much lower than the 19% of both independents and Democrats.

According to Newport, a belief in creationism is bucking the majority opinion in the scientific community - that humans evolved over millions of years.

"It would be hard to dispute that most scientists who study humans agree that the species evolved over millions of years, and that relatively few scientists believe that humans began in their current form only 10,000 years ago without the benefit of evolution," writes Newport. "Thus, almost half of Americans today hold a belief ... that is at odds with the preponderance of the scientific literature."

The USA Today/Gallup telephone poll was conducted May 10-13 with a random sample of 1,012 American adults. The sampling error is plus or minus 4 percentage points.
