Mars

Mars was one of the perfect planets for 3D, with breathable air, water and landforms like Earth. When the Orionians, Draconians and Reptilians came to Mars, the planet was devastated by wars.

 3,200,000 years ago when Maldek was totally destroyed, also by the warring factions, 10,000,000 million souls incarnated on Mars and on Earth, most of them on Mars. 

Out of about 100,000,000 souls who lived on Mars, about 10,000,000 survived the wars and took refuge underground. The artifacts of the civilizations on Mars are still visible, but NASA's betrayal prevents us from seeing them. A few brave scientists broke the tide of silence and misinformation and proved that they exist, e.g. Richard Hoagland. 

 Some of the underground cities are still inhabited today. The remaining 90,000,000 came to Earth through reincarnation.
