I was trying to say the day and the week were defined before Genesis was written making the latter reference the former thus conflicting with science.

I think I get what you're saying, I just meant that in general every time a scientific theory and a religious theory have coincided science has won (the heliocentric solar system for example)

A Creationist is someone who believed God created everything and everyone in 7 days according to the Genesis account - they are often disbelieving of evolution by natural selection and the possibility of the Big Bang
