Creationists believe that everything on Earth and in the universe was created by a supreme being.
Every ten years the Texas State Board of Education adopts new textbooks, a process that begins with a review team that judges each book based on curriculum standards.
Dan Quinn with the Texas Freedom Network said much of that review board is made up of creationists that discount evolution.
"It’s important that public schools teach kids 21st century science that prepares them to succeed in college and to succeed in the jobs in our modern era," Quinn said. "We don’t need 18th century science being taught in 21st century classrooms."
