"There are just too many quality sightings recorded by witnesses that need to be taken into account - people like presidents, people of high education that have seen things," Wayne Herschel, author of The Hidden Records and the Cosmic Tree told News24.
He said that human ancestry is tied to extraterrestrial beings from a distant star system and UFOs have been seen and depicted since ancient times.
"Every single human being is a descendant of those that colonised this world and my book shows you the star maps.
"This matches all the ancient records of the flying hats and the modern even are being more frequently seen because everybody's carrying around a camera," he said.
Mainstream researchers generally accept that unexplained phenomena are seen in the sky, but do not accept that these are linked to travellers from outer space.
Herschel insisted that it would only be a matter of time before there was irrefutable evidence for alien beings visiting Earth.
"We're getting a lot of good snippets from time to time, but there hasn't been anything really breaking that has filmed that we can say is 100% yet. I think it's probably a matter of time."
Astronomers told News24 that many observers who see strange objects in the sky may mistake clouds, unusually bright planets and even aircraft for UFOs.
"Big culprits here are Venus and Jupiter in particular, since they can be quite bright at times. Venus sometimes appears very bright in west shortly after sunset. At other times it's very bright in the east a few hours or so before sunrise.
"Also when a bright planet is low in the atmosphere is twinkles more than usual, and can appear to change colour rapidly. Sometime people describe it as 'being on fire'," said former SAAO astronomer Dr Enrico Olivier.
Hershel disputed that astronomers had the capacity to examine the entire night sky.
"If you look at astronomers' point of vision: Wherever they looking, they're looking at a tiny fraction of the sky at a time. They can't look at the whole sky, which is what you need to keep your eye on to see anomalies," he said.
He said that astronomers and other experts that studied the sky could not afford to confirm sightings of UFOs because they would place their professional careers at risk.
"Ask any academic person who has broken that code and supported UFO phenomena in any particular case; you will see the kind of trouble they get into: Their grants fall away. People are not taken seriously among peers; it is still taboo."
He slammed organisations that did studies into unexplained phenomena for conducting a "code of silence" where professionals were convincing witnesses to remain silent on what they saw.
"Big organisations that supposedly research UFOs to release information on UFOs are tied into government organisations that go in and see the person that's made the report.
"They want to put them under hypnosis and I'm pretty sure that there and then, they are covering up and hypnotising the person to forget what they saw."
The organisation Saufor (South Africa's UFO Resource) is a platform for South Africans to report UFO sightings, but there aren't many reports on its website.
"People don't want to report them anymore. If you look at how many people are seeing things, and one brave person will try and phone up an organisation or even try a police with a police report. But this kind of thing isn't reported much," said Herschel.
"It's going to keep going until the day comes when they actually park atop Table Mountain and people are filming and watching it. That will be the day," he added.
He said that extraterrestrials were concerned with suffering on Earth, but were prevented from making direct contact with humanity by world elites.
"The most important thing that the elite of the world are trying to cover up is an official visitation by them. They do not want them to show themselves because it will bring in peace and order and stability and no profiteering."
Herschel maintained that prophecies reveal a date when extraterrestrials will make their presence known.
"2012 makes the most sense with prophecy. The Mayan calendar ends on that date; Nostradamus prophecies all speak about a time close to World War III. The Revelation prophecies speaks of a situation that seems to match pretty much with the chaos that we're in now."
Herschel will be speaking at the UFO, Science And Consciousness Conference Johannesburg from November 25 - 27.
