Notable scientists -- such as Isaac Asimov, in his 1974 book Asimov on Astronomy -- have also wondered how the Earth was able to capture a body as large as the Moon.
Scientists obtained evidence that the Moon is hollow when they crashed a spacecraft on its surface and it generated an explosion equivalent to a ton of TNT in November 1969, Icke claimed.
Scientists were amazed when sensors showed the shock wave of the impact ringing like a bell or gong, suggesting the Moon was a hollow structure, Icke said.
Icke was referring specifically to an experiment conducted by the Apollo 12 crew called the Passive Seismic Experiment. They crashed the Apollo 12 Lunar Module on the lunar surface on November 29, 1969. Astronomers and physicists were surprised that the reverberations generated by the crash propagated for nearly an hour.
The experiment was repeated during the 1970 Apollo 13 mission. The impact reportedly created moonquake reverberations that lasted for more than three hours, compared to only a few minutes even during earthquakes.
A NASA document about the experiment remarked that "Nothing comparable happens when objects strike Earth."
The observation caused a debate among scientists about the nature of the interior of the Moon.
"These two Russian scientists from the Society Academy of Science wrote an article in 1970 in Sputnik magazine in Russia headed, 'Is the Moon the creation of an alien intelligence?'" Icke continued. "And all these years later it indicates to the fact that they were right."
Icke went on to argue that the outer shell of the hollow moon is very hard and consists of several substances that do not occur naturally.
"The surface is a poor heat conductor. This space ship of ages long past we call the Moon is superbly constructed," he said. "If you are going to launch an artificial sputnik, it is advisable to make it hollow."
The Russian researchers, Vasin and Shcherbakov, had claimed that evidence that the Moon consists of a tough artificial inner shell comes from the observation that craters formed by meteor impacts tend to be shallower than expected, and the bottoms tend to have a convex or flat shape.
This suggests that the inner shell of the Moon is tougher than expected for naturally occurring materials.
The researchers suggested that the Moon's inner shell was probably about 20 miles thick and protects an inner cavity with an atmosphere that supports alien astronauts.
Other theorists who supported the Artificial Moon Theory include, Don Wilson, author of the 1975 book, Our Mysterious Spaceship Moon, and George H. Leonard, in his 1976 book, Someone Else is On the Moon.
Supporters of the theory often quote NASA scientist Gordon MacDonald, who allegedly said that "[T]he data require that the interior of the Moon is more like a hollow than a homogeneous sphere."
Others quote MIT's Sean Solomon who reportedly wrote in a report on the Apollo Passive Seismic Experiments that "the Lunar Orbiter experiments vastly improved our knowledge of the Moon's gravitational field... indicating the frightening possibility that the Moon might be hollow."
Icke concluded that everything we know about the Moon suggests intelligent design and that it is an ancient spaceship with a spacious interior that contains the engines, control rooms, cabins and power plants of an ancient spaceship.
The size of the spaceship, according to Icke, suggests it was designed as an interstellar or intergalactic craft capable of accommodating generations of space-faring astronauts wandering across galaxies over millions of years.
Icke, a former footballer, has been a controversial figure since he revealed to the world that he was the "son of the Godhead." He has been a prominent figure in the conspiracy theory movement, having given many lectures on his outlandish conspiracy theories and written many books promoting his beliefs over more than two decades.
