In some corners of this world, there still exist customs that are hard for modern people to believe.
Eating unburied corpses, using skulls as cooking utensils, and consuming human flesh in dark magic rituals are just part of it.
While these might sound like scenes from a horror movie, for the existing cannibal tribes in the world, this is part of their daily life. 
These tribes usually reside in corners of the world untouched by modern civilization, thus their lifestyle and traditions can be traced back thousands of years.
Their existence is full of mystery and allure for scientists and explorers, although sometimes this allure might come at the cost of life.
The exploration by MailOnline has given us a deeper understanding of these cannibal tribes.
In the northern Indian city of Varanasi, members of the Aghori sect are notorious for their customs of eating human flesh and using human remains.
They use the remains of the dead thrown into the Ganges for their activities, using skulls as drinking vessels, believing that such practices bring them closer to the divine.
One follower’s home uses an empty coffin as a shelf, with a gym bag full of human skulls at the foot of his bed.
Polish photographer Jan Skwara’s documentation reveals that although this tribe worships the Hindu god Shiva, their practices are starkly different from orthodox Hinduism.
In New Guinea, the Asmat tribe is known for its headhunting and cannibalistic customs.
They believe that by eating the brains of their enemies, they can gain the deceased’s power.
The tribe members often paint their faces with oil, wear decorative headdresses, and carry spears, making a profound impression.
There are many legends and speculations about their traditions, including rumors that they might have eaten Michael C. Rockefeller, the son of New York Governor Nelson Rockefeller.
The Korowai people, another tribe from Papua Province in Indonesia, were unaware of anyone else’s existence until the late 1970s.
Their lifestyle differs greatly from the outside world, with reports claiming they were cannibals, though this claim is controversial.
The Sentinelese people might be the most fitting image in our minds of remote, isolated tribes.
Living on North Sentinel Island in the Bay of Bengal, they are the world’s last Stone Age tribe.
They are extremely hostile to outsiders, to the extent that the Indian government prohibits anyone from entering within five nautical miles of these islands.
In 2018, American Christian missionary and explorer John Allen Chau met his unfortunate end while attempting to contact the Sentinelese, further proving the tribe’s dangerous nature.
Although the customs of these tribes might shock modern society, we cannot ignore the fact that their way of life is part of human diversity, and their traditions and beliefs are manifestations of their millennia-old cultures.
Our understanding of them should not be based solely on fear and prejudice but on respect and comprehension.
After all, the existence of these tribes reminds us that, despite the world becoming smaller, we still live in a diverse and complex world.
