The only ancient world wonder that still exists is the Great Pyramid of Giza
The Seven Wonders of the Ancient World is the first known list of the most remarkable creations of classical antiquity; it was based on guidebooks popular among Hellenic sightseers and only includes works located around the Mediterranean rim and in Mesopotamia.

The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it was the number of the five planets known anciently, plus the sun and moon. Many similar lists have been made.

The historian Herodotus (484 – ca. 425 BC) and the scholar Callimachus of Cyrene (ca. 305–240 BC), at the Museum of Alexandria, made early lists of seven wonders. Their writings have not survived, except as references.

Great Wall of China (Since 7th century BC), China

Petra Ma'an (312 BC), Jordan

Colosseum (AD 80), Italy

Chichen Itza c. (AD 600), Mexico

Christ the Redeemer Opened (October 12, 1931), Brazil

Machu Picchu c. (AD 1450 ), Peru

Taj Mahal (AD 1648), India

In 2000 a Swiss foundation launched a campaign to determine the New Seven Wonders of the World. Given that the original Seven Wonders list was compiled in the 2nd century BCE—and that only one entrant is still standing (the Pyramids of Giza)—it seemed time for an update. And people around the world apparently agreed.

The results were announced on July 7, 2007, in Lisbon, Portugal.

Canadian-Swiss Bernard Weber created the “New Seven Wonders of the World Foundation” (N7WF) and launched a worldwide competition to create a new list.

The Great Pyramid of Giza, largest and oldest of the three pyramids at the Giza Necropolis in Egypt and the only surviving of the original Seven Wonders of the Ancient World, was granted honorary status : Completed c. 2560 BC, Egypt  

Not 7th wonder and it is not at all a wonderful thing
While many do not care for their parents, some on earth purposely do not see their father, grand father, father in law who has left life but is about to leave this earth. Science increases age. They are so short thinkers & egoistic that they forget that a day will come when they become grand parents or parents.

As of now there are humans on this planet
and if we see them on another planet one day, we hope they dont have such human attitude.
