Why I left young-earth creationism by Glenn Morton
https://peacefulscience.org/articles/glenn-morton/
I read this blogpost eons ago, this is about a well respected young-earth creationist come-to-the-light moment when he realized the data doesn't match his Christian beliefs. This is very well written and a proof that changing mind when confronted with facts is indeed possible.
This is mostly about flood geology and the age of the earth so I don't know if the mods will allow it but I thought it was a very interesting text. Enjoy
