Convinced that the object was a flying saucer, and hearing of other sightings at the same time in São Paulo, Paraná, Argentina, Bolivia and Paraguay, he decided to undertake a deeper study of UFOs.

"[8] Speaking at the Australian International UFO Symposium in Brisbane, Queensland, Australia in October 1996, he discussed two aliens allegedly captured by the army after their space vehicle crashed in Varginha, Brazil on 20 January 1996.

The description of one of the creatures was similar to that of the standard short grey alien, but it had greasy brown skin, red eyes and protuberances that could have been horns.

[11] Answering questions from the audience during a 2001 talk show, he described the great advances that had been made in ufology in recent years, and particularly in Brazil, which he described as a leading center of research.

[13] He discussed two flying saucer videos created by French-American artist, Barzolff and said "It was the largest UFO phenomenon over the past 10 years.

He said that unmasking fraud is a major job for ufologists, easy to produce and release videos makes it difficult to separate what is fabricated from what is just inexplicable.

He said the problem is that the governments of various countries treat the issue as something top secret, but expressed hope that policy makers were beginning to change their attitude.

A police officer said "it is clear that the action was premeditated and carried out by elements that had knowledge of the activities of UFO Magazine, experience with computers and knew where to find the company's most important files."

That week the magazine launched its 25th DVD documentary, The Phoenix Lights, depicting one of the largest UFO waves in the news, in March 1997, in the city of the state of Arizona, USA.

[18] Gevaerd was a keynote speaker in June 2008 at the first International Meeting of ufology experts in Lisbon, discussing the Varginha UFO incident.

[20] He was slated as a speaker at the 18th Annual International UFO Congress Convention and Film Festival in Laughlin, Nevada in February 2009, speaking on the need for the public to demand that the government release information about extraterrestrial life.

[21] Discussing UFO sightings and crop circles that appeared near Riolândia, São Paulo in January 2000, he said that the bent reeds were not evidence.

[25] Gevaerd said that one of the reasons why ufologists do not let themselves be discouraged by lack of proof for their theories is due to the fact most of them believe in the existence of a government conspiracy to hide the truth from the people.

[27] In August 2008 Gevaerd stated that the government has plenty of information that UFOs enter Brazilian air space every day, but refuses to publish it.

[6] Discussing the campaign for release of government information, at a September 2008 meeting of UFO enthusiasts he stated, "We are being visited by many civilizations from other planets.

[34] Commenting on some initial documents released by the Air Force on 20 March 1996 sightings of UFOs in five cities in southern Brazil, he said "It's just the tip of the iceberg."
