Aliens visited Earth through a volcano "wormhole".
UFO expert Jaime Maussan claims that two spacecraft flew into the Popocatepetl volcano in Mexico when its crater fired lava into the air.
The ufologist shared video footage of the incident and claimed that no man-made object would be able to cope with the 1,000C heat inside the crater.
Maussan considers Popocatepetl to be a gateway between two locations in space and time and believes that the magnetic force within the volcano acts as a wormhole to other places in the universe.
The journalist said: "In 1996, the University of Bergen in Norway discovered under the volcano there are magnetic storms necessary to be able to generate X-points or regions of electron diffusion and be used to create a dimensional portal."
Maussan added that the idea of wormholes was first put forward by the celebrated physicist Albert Einstein back in the 1930s.
