What year was the egg first used for cooking?

It's impossible to say exactly when the egg was first used for cooking. Humans have been eating eggs for thousands of years, long before written records existed.

Here's what we know:

* Archaeological evidence: Shell fragments from bird eggs have been found in archaeological sites dating back to the Stone Age.

* Early civilizations: Ancient Egyptians, Greeks, and Romans all consumed eggs as a food source.

* Cooking methods: Early cooking techniques likely involved roasting eggs in the ashes of a fire or boiling them in water.

Therefore, while we can't pinpoint the exact year, it's safe to say that eggs have been a part of the human diet for a very long time, predating written history.
