'Crazy' simulation shows how man found ancient underground city after knocking down basement wall

People have been left mind-blown by an impressive simulation showing what it would have been like for a man who discovered an ancient city under his home.

Many of us have no idea what's really underneath our homes, with some having discovered bodies beneath their properties.

Elsewhere, a woman found a huge tunnelling system that was located 22 feet beneath her house.

But this man found something extremely unexpected - an ancient city dating back to 1200 BC.

The huge discovery was made by a man in Derinkuyu, Turkey when he was renovating his property in 1963.

The guy in question had noticed something peculiar about his home; his chickens kept disappearing into thin air.

Determined to find out where they were going, he stumbled upon a small crevasse that had formed in his basement that he realized the birds were escaping through.

He then decided to knock down the wall and ended up unearthing an entire ancient city which had more than 600 entrances.

YouTuber Zack D. Films has since created a simulation of what it would have been like to experience finding the forgotten city, and it's safe to say it's left people gobsmacked

Inside the city were schools, stables and even wine cellars, in addition to ventilation shafts and escape routes.

It's believed to have been used for refuge during wars and invasions.

People who have only just learned about the historic find have since shared their shock.

"Imagine having a whole city in your basement," one person on YouTube said.

Another person pondered: "It's kinda creepy knowing there might be more ancient cities out there that we haven't discovered yet."

"Accidentally finding an ancient city is crazy," a different person commented on the simulation.

Someone else went as far as suggesting the ancient city could be a plot to a movie.

They penned: "Is it just me or does this sound like the plot to a indie horror game where you explore the tunnels while a monster is stalking you."

I mean, I'd watch it.

While the famous underground city hasn't been in a movie, it has featured on the Netflix series Ancient Apocalypse in an episode titled 'A Fatal Winter'.

The series synopsis reads: "Journalist Graham Hancock travels the globe hunting for evidence of mysterious, lost civilizations dating back to the last Ice Age."

Ancient Apocalypse, which has two seasons that are available to stream, has a 75 percent score on Rotten Tomatoes.

The episode about the underground city in Turkey features in season one.
