(CNN) - Republican Sen. Marco Rubio of Florida attempted to clear up Wednesday his controversial answer to a question about the Earth's age last month.
"Science says (the Earth) is about 4.5 billion years old. My faith teaches that's not inconsistent," Rubio said at a Politico Playbook Breakfast in Washington. "God created the heavens and the Earth, and science has given us insight into when he did it and how he did it."

"The more science learns," he continued, "the more I am convinced that God is real."
Rubio was asked how old the planet was in an interview with GQ magazine published November 19. The senator, who's considered to be weighing a 2016 presidential bid, replied saying the Earth's age is "one of the great mysteries."
Emphasizing he "was not a scientist," Rubio said "whether the Earth was created in seven days, or seven actual eras, I'm not sure we'll ever be able to answer that."
His comments received fierce pushback in the liberal blogosphere and brought renewed attention to the debate between creationism and evolution.
On Wednesday, one morning after he gave a high-profile speech, Rubio said he doesn't "regret" his answer but wishes he had given "a more succinct" response.
"We were talking about hip hop and the guy pivoted to the age of the Earth," the junior senator said. "I'm not a robot." He added that if he had 30 minutes to sit down and write out his thoughts, he would have provided a better answer.
"It's not the worst thing that's ever happened to me," he said
Rubio said he was originally talking about the "theological debate" over the Earth's age-not the "scientific debate," which he said has definitively established the planet is at least 4.5 billion years old.
He emphasized it was a matter of "how do you reconcile what science has definitively established with what you may think your faith teaches" and further maintained his stance that parents should be able to teach their children whatever they believe.
He also pointed to then-Sen. Barack Obama's answer to a similar question in 2008.
"My belief is that the story that the Bible tells about God creating this magnificent Earth on which we live, that that is essentially true, that is fundamentally true," Obama said at a CNN presidential forum. "Now, whether it happened exactly as we might understand it reading the text of the Bible? That, you know, I don't presume to know."
A Roman Catholic, Rubio also attends Baptist services and added Wednesday that he sometimes goes to both churches in one day.
Asked why he thought his original comments caused such a stir, Rubio argued that he enjoys it when something he says triggers conversation but added he didn't think the dialogue made it far beyond the Beltway.
"Not a single person at the supermarket asked me about it on the day before Thanksgiving," he said.
