Gary Bates used to believe in evolution. However, upon his conversion to Christianity he had difficulty reconciling the so-called "facts" of evolution with the teaching of the Bible. Through his journey of personal discovery, he has explored many of the issues surrounding the creation and evolution debates, and for over 15 years, he has worked both as a volunteer and staff member of Answers in Genesis in Australia as a featured speaker and now serves in its ministry development activities. His conclusions have sparked controversy in the Christian community because he is not afraid to address issues surrounding UFOs and aliens unlike most mainstream denominations.
Author of Alien Intrusion, Gary Bates presented his analysis of UFOs & alien abductions, as seen through a strict Biblical interpretation. He also discussed creationism, and laid out his case that Earth and the universe itself are only 6,000 years old. He backed up this assertion by citing genealogical records in the Bible, as well as mentioning the work of Dr. Russell Humphreys.
