Steve Preston is a prolific author on a wide range of historical, religious and scientific subjects; just look at his page on Amazon(a). Unfortunately, he should have concentrated on quality rather than quantity. His work is comparable with that of von Däniken, including the use of many of the same questionable sources.
He frequently refers to Atlantis[1263/4/5], placing it in the Atlantic, influencing the Egyptian civilisation and being destroyed around 10,000 BC. He also devoted one of his offerings to supporting the idea of an Egyptian link with Ireland!
