Ice, in the everyday sense (frozen water), has existed naturally on Earth for billions of years, since the planet was cool enough for water to freeze, long before humans appeared. Humans have been deliberately making, storing, and using ice for at least a few thousand years.

Natural ice on Earth

  • Liquid water can freeze into ice whenever temperatures reach 0°C (32°F) or below at standard pressure, a process that would have occurred as soon as early Earth cooled enough to sustain surface water.
  • Geological and climate evidence shows repeated “ice ages” over the last few million years, during which vast ice sheets covered large parts of the continents.

Early human use of ice

  • Ancient civilizations were cutting and storing natural ice at least 2,000–3,000 years ago, using it to cool food and drinks and preserve perishables.
  • By around 400 BC, engineers in ancient Persia built yakhchals , large dome-shaped underground structures designed specifically to store winter ice through the scorching desert summers.

“Created” ice by technology

When people ask “when was ice created,” they often mean “when did humans first make ice on purpose with machines?”

  • In the mid‑1800s, inventors built the first mechanical ice-making machines, allowing artificial ice production regardless of season.
  • In 1851, physician John Gorrie patented an ice machine in the United States to cool fever patients, and within a few decades commercial icemakers were producing thousands of kilograms of ice per day.

A quick way to phrase it

  • Natural ice: as old as the first frozen water on early Earth, billions of years ago.
  • Human use of natural ice: at least a few thousand years.
  • Machine‑made ice: developed in the 1800s, with key patents in the 1850s and commercial growth later that century.
