Old Earth creationism (OEC) is an umbrella of theological views encompassing certain varieties of creationism which may or can include day-age creationism, gap creationism, progressive creationism, and sometimes theistic evolution.
Broadly speaking, OEC usually occupies a middle ground between young Earth creationism (YEC) and theistic evolution (TE). In contrast to YEC, it is typically more compatible with the scientific consensus on the issues of physics, chemistry, geology, and the age of the Earth. However, like YEC and in contrast with TE, some forms of it reject macroevolution, claiming it is biologically untenable and not supported by the fossil record, and the concept of universal descent from a last universal common ancestor.
