Alien Footprint: Namib is the largest desert of Namibia, the country of Africa. On the desert surface, millions of circles are scattered and evenly spaced. Grass in the circumference of the circle can be as high as the knee but not grow inside even when the soil is fertilized. Each circle can reach a diameter of 2-20 m. This strange circle appears on a distance of 1,800 km. Photo: Bles.

When researchers have not yet figured out the cause of these mysterious circles, local people came up with many theories. They believe they are made up of souls and are the footprints of the gods. Hein Schultz, the owner of a hotel outside Namib-Naukluft National Park, said: "Some locals believe these mysterious circles are created by UFOs or fairies dancing in the night that created them".

The oldest desert in the world: According to BBC, Namib dating back at least 55 million years, is considered the oldest desert in the world (Sahara desert is only 2-7 million years old). With summer temperatures often up to 45 degrees Celsius and nights below freezing, this is also one of the harshest places on the planet. Photo: Maxim Babenko.

"Hell's Gate" is said to be one of the most dangerous areas in Namib. This harsh place is a 500 km wide land with soaring sand dunes and a rusty ship along the Skeleton Coast. Many whale carcasses and nearly 1,000 shipwrecks have been scattered on this coast for centuries. This area is often covered by dense fog that puts boats in danger. Locals call this area "the land God created in anger". Photo: TravelDigg.

Orange sand dunes: Sossusvlei, a vast salt pan in the center of Namib-Naukluft National Park, is covered by bright orange. This color is formed by rust and is a sign of oxidation due to the high iron concentration in the sand. Some of the dunes in this area are believed to be the highest in the world. The orange sand dunes are from 200-400 m high. Photo: Oleg Znamenskiy.

Animals resist the rigors to survive: Namib's most arid regions receive only an average of 2 mm of rain a year. For a few years, this place did not catch any rain. However, resilient animals like the horned antelope, the jumping antelope, the cheetah, the hyena, the ostrich, and the zebra have adapted to survive in extreme conditions. Photo: Radek Borovka.

According to research, ostriches survive in this environment by increasing body temperature to reduce dehydration. Hartmann mountain zebras are adapted to the rugged desert terrain. The scimitar oryx can endure for weeks without drinking water. Instead, they eat water-rich foods like roots and tubers. Photo: Matthias Kestel.
