This article from Answers in Genesis gives some good information about why six literal creation days is Biblical and why we should reject evolution and an old Earth of millions or billions of years in age: https://answersingenesis.org/death-before-sin/six-days-or-billions-of-years/

Another good (and entertaining) resource about evolution is the video from Living Waters where Ray Comfort talks to both students and academics on the topic. You may watch “Evolution vs God” for free here: https://www.livingwaters.com/movie/evolution-vs-god/
