Washington (CNN) – Florida Sen. Marco Rubio attempted to walk the line between science and faith-based creationism in remarks that that have provoked the ire of liberal blogs, leaving the door open to creationism in responding to a recent question about the age of the Earth.

When GQ’s Michal Hainey asked Rubio, in an interview released Monday, “How old do you think the Earth is,” the rising Republican star described the debate about the planet’s age as “one of the great mysteries.”

“I'm not a scientist, man,” Rubio told the interviewer. “I can tell you what recorded history says, I can tell you what the Bible says, but I think that's a dispute amongst theologians and I think it has nothing to do with the gross domestic product or economic growth of the United States.”

“Whether the Earth was created in seven days, or seven actual eras,” Rubio continued, “I'm not sure we'll ever be able to answer that. It's one of the great mysteries.”

Most scientists agree that the Earth is 4.5 billion years old and the universe is 14.5 billion years old. Christian Young Earth Creationists, on the other hand, argue that the weeklong account of God creating the Earth and everything in it represents six 24-hour periods (plus one day of rest) and date the age of the Earth between 6,000 and 10,000 years.

Left-leaning blogs and sites like ThinkProgress and Huffington Post jumped on Rubio’s comments, with the Zack Beauchamp from ThingProgress writing, “To suggest we can’t know how old the Earth is, then, is to deny the validity of these scientific methods altogether — a maneuver familiar to Rubio, who also denies the reality of anthropogenic climate change.”

Rubio is regarded as a possible Republican presidential candidate in 2016, though the senator says his visit last week to Iowa, home of the first-in-the-nation presidential caucuses, had “nothing to do with 2016.”

His response to GQ’s age of the Earth query has also provoked questions about his political aspirations. Dave Weigel of Slate writes, “How can you read that and not think ‘Iowa’? ” The state is the first to hold a presidential caucus in 2016.

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 in June. That number has remained unchanged for the past 30 years, since 1982, when Gallup first asked the question on creationism versus evolution.

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.

The Gallup poll has not specifically asked about views on the age of the Earth.

Rubio attends a Baptist church in southern Florida but also considers himself “a practicing Catholic.”

He was born Catholic, but his family converted to Mormonism when Rubio was 8 years old, according to Rubio’s recent memoir. The family left its LDS faith behind when it moved from Nevada back to Florida and Rubio was confirmed in the Catholic Church.

Catholic teaching is that science and faith are not at odds with one another and it is possible to believe what scientists say about the Earth’s age and in God. But many evangelical churches, including Baptist ones, promote a version of creationism.

When CNN reached out to Rubio’s Baptist church in Florida on Monday, a person answering the phone would not comment on its teachings about the Earth’s age and said that a church representative was unlikely to be available in the near term.

During the GQ interview, Rubio argued that “there are multiple theories out there on how the universe was created and I think this is a country where people should have the opportunity to teach them all.”

For the past 30 years, the “equal-time argument” –- the idea that Creationism taught alongside evolution -– has been popular method for Creationists to advance their cause. In the late 1980s, some state legislatures passed bills that promoted the idea of a balanced treatment of both ideas in the classroom.

In 1987, the issue made it all the way to the Supreme Court, where a Louisiana "equal-time law" was struck down. The court ruled that teaching creationism in public school classrooms was a violation of the Establishment Cause in the Constitution, which is commonly referred to as the separation of church and state.
