Creation Scientists take a literal approach to Genesis 1, believing it to be an actual account of the creation of the universe. They use science to back up this view. The Institute for Creation Research (ICR) was created to complete research into backing up this theory.
Founded by Dr. Henry Morris in 1970, ICR exists to conduct scientific research within the realms of origins and Earth history, and then to educate the public both formally and informally through graduate and professional training programs, through conferences and seminars around the country, and through books, magazines, and media presentations.
We will look at some of the main beliefs held by the ICR in upcoming posts but just now we will look at the idea that the universe is just a few thousand years old.
There are many different pieces of evidence for this theory put forward including the dating of comets, the lack of salt in the sea floor and the soft tissue in fossils. See the below image. A lot of the explanations are quite complex and so providing you are able to summarise the young earth theory and perhaps remember a few of the supporting evidence.
