Name the ancient civilization known for its pyramids and hieroglyphics.

The ancient civilization recognized for its pyramids and hieroglyphics is Ancient Egypt. This civilization, thriving along the Nile River, is renowned for its monumental architecture, particularly the pyramids, which served as elaborate tombs for pharaohs. The Great Pyramid of Giza is one of the most iconic structures from this era and exemplifies the advanced engineering and organizational skills of the Egyptians.

Hieroglyphics, a system of writing using symbols and images, was developed by the ancient Egyptians for various purposes, including religious texts, record-keeping, and monumental inscriptions. This form of writing was integral to their culture, conveying stories, religious beliefs, and historical events.

In contrast, Mesopotamia is noted for its ziggurats and cuneiform writing but lacks the iconic pyramids and hieroglyphics associated with Ancient Egypt. The Indus Valley Civilization is recognized for its advanced urban planning and drainage systems but did not utilize hieroglyphics or construct pyramids. Finally, Ancient Greece contributed significantly to philosophy, democracy, and various art forms but is not associated with pyramids or hieroglyphics either.
