Chaco Canyon
Angkor Wat
Today we know a lot about the world, but
there is also a lot we are still learning.
How did people in the ancient world
build monuments without modern
tools?
Have aliens visited Earth?
What happened to lost cities like
Angkor Wat, Atlantis, and Chaco?
Mysterious Monuments
have always wanted to create things. They
made fire, built crude tools, and wrote on cave
walls. Then people began to think bigger. They made
monuments. Statues are monuments made to honor
someone. Early monuments paid respect to gods or
rulers. Other statues were built to honor the dead.
New technology helped people build great stone
structures. And now, these amazing places are
proof of ancient human creativity.
Technology Through the Ages
Technology is anything that humans use
to solve problems or make work easier.
People first used technology when they
turned sticks and stones into simple
tools. Making fire was an advance in
technology. So was the invention of the
wheel. These were major technological
discoveries in prehistoric times.
Sacred Stones
Stonehenge as
viewed from
above
A circle of huge stones rises from the plains
of England. This ancient monument is called
Stonehenge. It has puzzled people for centuries.
Scientists know it was built 5,000 years ago. But
everything else is a mystery. How did the builders
move the huge stones? Some weigh more than
tons. And they came from miles away! How did
they stack them? And why did they work so hard to
build this monument?
Some people think Stonehenge was a calendar.
Many points match up with astrological events.
Others say this was a burial place. Archaeologists
have found human bones at the site.
Other Ideas
The most accepted theory
today is that Stonehenge
was a burial site for
ancient leaders. A more
far-fetched theory suggests
Merlin, the magician from
the King Arthur legend,
used magic to move the
stones. Others say that
aliens placed the stones.
Ancient Calendar
In 1965, an astronomer named Gerald
Hawkins wrote a book called Stonehenge
Decoded. In it, he linked points at the site
to astrological events. For example, at dawn
on the summer solstice , the center ring, two
nearby stones, and the sun all line up.
Where Kings Rest
Between 3,000 and , Egypt was a vibrant
place. Thousands of people lived along the Nile River.
Their culture was rich and full of mysteries.
Today, millions of people visit Egypt every year.
Many go to see the Great Pyramid of Giza. It was built
4,500 years ago. It was a royal tomb for Pharaoh
