Our ancestors were extremely creative. Archeologists keep making discoveries. Some of the things they find and see look incredibly mysterious.

1. Stonehenge

Stonehenge has been one of the greatest attractions for many centuries. It is located in England. The monument is said to be 5000 years old. The structure consists of many large and small stones. The largest pieces have a height of 30 feet. Their weight is 25 tons and they are called sarsens. No one knows why this structure was created. It is reported that the ancestors brought the stones from Preseli hills – the area located around 150 miles away from the monument.

2. Nazca Lines

Pay attention to the formation of white lines that you will see when you make a flight over the desert of southern Peru. The lines have been included to the list of UNESCO world heritage places. The lines resemble swirls, triangles, rectangles, and trapezoids – quite unusual and even mysterious formations that have interesting shapes and forms. You will also notice hundreds of geometrical shapes as well as plant structures and seventy animals. No one knows for sure who and why created them. Some believe that the lines were made by Nazca Indians 2 thousand years ago. Some say that Nazca lines were created by aliens.
