Here are some of his notable works:
* The Genesis Flood (1961): This book, co-authored with John C. Whitcomb Jr., is considered a seminal work in young-earth creationism. It argues for a literal interpretation of the Genesis creation account and a global flood as the primary mechanism for the formation of geological features.
* Scientific Creationism (1974): This book outlines the creationist perspective on various scientific disciplines, including geology, biology, and astronomy, arguing that they are consistent with a literal reading of Genesis.
* The Biblical Basis for Modern Science (1984): In this work, Morris argues that modern science was fundamentally influenced by the biblical worldview.
* The Long War Against God (1989): This book explores the historical development of ideas that have challenged the biblical worldview, including evolution, humanism, and secularism.
He also contributed extensively to the creationist movement through articles, books, and speeches.
It's important to note that Morris's views on creationism are controversial and not scientifically accepted. While he presented his arguments as scientifically sound, the scientific community overwhelmingly supports the theory of evolution.
