The world is filled with a large amount of mystery and new things are being discovered every day. Whether it be in places that are common like the dense forests of South America or something that we as humans haven't even scratched the surface of yet, like the ocean, there are so many things left in the world to be discovered. Scientists to archeologists and everything in between have been finding things like large tunnels that interconnect under Europe to things like ancient tombs in China. What most of these things have in common is the fact that scientists still can't explain how they came to be and it is something that is still being researched even today.

While there are so many strange findings on Earth and more are being discovered every day, here are 25 that we've narrowed down to be the most intriguing and the most mysterious. Things like ancient civilizations to strange lines that were formed in Peru taking up most of the landscape, here are 25 mysterious things that leave scientists baffled even to this day.

Scientists have dated this strange wall to the Nabataean period and the Umayyad period.

9 Aluminum Wedge Of Aiud In Romania

This strange formation was first discovered in 1974 and was deemed the Aluminum Wedge of Aiud. They've discovered that the rock is miraculously made of 89 percent aluminum.

The project took around 28 years to complete and it is a huge tourist spot!

7 The Antikythera Mechanism, Found In The Aegean Sea

The device has several different gears made out of several different materials.

6 The Loch Ness Monster, Sighted In Scotland

The large dinosaur-like creature is said to be swimming around in Lake superior in Scotland. Much like Bigfoot, the Loch Ness Monster's most convincing evidence was a grainy photo showing a long-necked sea creature emerging from the water.
