Michel Desmarquet is known for his book 'Thiaoouba Prophecy', also known as 'Thiaoouba: The Golden Planet'. He was born on July 16, 1931 in Normandy, France, to Claudumir and Georgette Desmarquet. Both of his parents worked as professional photographers. After finishing at an agricultural school, he joined the French Army, and was stationed in French Equatorial Africa at the age of 16. There, the free spirited young Michel used his innate sense of humor to spoil military discipline so that no disciplinary punishment had the intended effect.  When Michel was sent to a military prison there, he learned several local dialects from the African guards, and used his language skills to spoil the plans of recruiting Africans to the French army in Vietnam for the First Indochina War with great success. After returning to France briefly, he went back to Africa and spent several years managing coffee plantations and landscaping gardens.

Thereafter, Michel Desmarquet worked as a salesperson in France and married Lena, his first wife, at the age of 29 in 1960. Patricia and Peter, the two children mentioned in the book Thiaoouba Prophecy, were born from this marriage.   They spent their early years in Carpentras, France.

In 1971, Michel Desmarquet and his family moved to the French territory of New Caledonia, before moving to Australia in February 1971. In Australia, Michel lived a year in Brisbane and then purchased five hectares in Freshwater near Cairns and developed a farm, on which he grew vegetables commercially, ran a plant nursery, while raising a small number of livestock.

After selling the farm in 1985, Michel purchased 11.5 hectares in Deeral, about 44 kilometers south of Cairns, on the edge of a national park.  It was there he built a home, established another farm, and most importantly, was contacted by the people from Thiaoouba in June, 1987.

It took Michel Desmarquet three years to write the book 'Thiaoouba Prophecy', first titled 'Abduction to the 9th Planet'.  Further difficulties arose to sell the book, as few people, including the so-called UFO experts, believed him. Still, Michel managed to present his encounters and experiences in public lectures around Australia and the United States throughout the 1990s. Tom Chalko arranged lectures for Michel in Melbourne, Australia, including several at Melbourne University, and Michael Meanwell promoted Michel's visits by arranging media interviews.

Michel separated from his wife Lena in the mid 1990s and sold their property in 2000 after a divorce.

Michel then decided to go to Vietnam and there, he lived on an island in southern Vietnam, an island he said that reminded him a little bit of the planet Thiaoouba.  In 2004, he married Nga, his Vietnamese wife.
