Antikythera is an ancient machine made by Greeks more than 2000 years ago. It looks like a small box with lots of tiny gears inside. The machine was found in the Antikythera shipwreck in the Mediterranean sea in 1901.
This machine was a type of computer that could tell the time, date, and the positions of planets and stars in the sky. It was like a fancy calculator, but instead of numbers, it used the movements of the stars to track time and space.
The Antikythera machine was so advanced for its time that scientists still study it today to figure out how it worked. It was like a super-smart clock that needed no batteries, no electricity, and no internet to work.
Although it was made so long ago, the Antikythera machine is an amazing example of how smart and clever ancient Greeks were. It is a fascinating piece of history that helps us understand how humans have always tried to understand the world around them.
