Day-Age Creationism
Day-Age Creationism holds that the six days referred to in the
Genesis' account of creation are not ordinary 24-hour days, but rather much longer periods (of thousands or millions of years); the Genesis account is then interpreted as an account of the process of evolution. There are even some Christians who believe the six day period refers to the time spent by light traveling from the center of the universe at the time and point of creation.

Some material moved to Talk for work. While POV and not focused, it is useful material as it proposes some arguments for the day-age interpretation.
