Aliens, giants or magic - was it more exciting when the origins of Stonehenge were left a mystery?
Located on Salisbury Plain in England, Stonehenge is a prehistoric monument believed to have been constructed around 2500 BC.
Researchers have recently claimed Stonehenge is a giant solar calendar to help people keep track of the days, weeks and months, possibly solving one of the world's greatest mysteries.
One of the researchers, Professor Timothy Darvill from Bournemouth University, said the site was based on a solar year of 365.25 days, where weeks were 10 days long and there were more months than there are today.
"The proposed calendar works in a very straightforward way," Prof Darvill said in a media release.
"Each of the 30 stones in the sarsen circle represents a day within a month, itself divided into three weeks each of 10 days.
"Such a solar calendar was developed in the eastern Mediterranean in the centuries after 3000 BC, was adopted in Egypt as the Civil Calendar around 2700 BC, and was widely used at the start of the Old Kingdom about 2600 BC."
There have been many theories in the past as to how the rocks weighing up to 60 tonnes and 13 feet high came to be placed in an almost perfect circle.
According to folklore, Stonehenge was created by the wizard Merlin who magically transported the massive stones to England where giants assembled them.
Another theory is that Stonehenge is the ruins of a Roman temple or that it is a spacecraft landing area for aliens.
Yet rather than rejoicing in this new scientific discovery, it has left many people feeling disappointed.
This new discovery is "too boringly practical instead of mysterious", one person wrote on Facebook.
"So Stonehenge was a solar calendar, in that case why didn't the aliens put it somewhere there was actually some sun?" one user said on Twitter.
"They could of just stuck a stick in the ground but this seems a lot more decorative," one person tweeted.
So maybe this "old calendar" isn't everyone's cup of tea.
