There are so many amazing places on Earth, both man-made and natural, but some of them look like they are alien and don’t actually exist. For example, the “Door to Hell” in Turkmenistan that is 69 meters (226 ft) wide, or a casting pool in San Francisco that reminds us more of a secret extraterrestrial garden. When you look at them, you can’t believe you are actually still on our planet.
