Who invented beer?

It's impossible to pinpoint a single inventor of beer. The history of beer dates back thousands of years, and it's likely that the process of brewing was discovered independently in different parts of the world.

Here's what we know:

* Ancient Mesopotamia: The earliest known evidence of beer production comes from Mesopotamia around 7000 BCE. This suggests that beer was already well-established in ancient Sumerian culture, and likely even predates that date.

* Ancient Egypt: Beer was a staple beverage in Ancient Egypt, and there's evidence of beer production dating back to 3500 BCE.

* Other Early Civilizations: Evidence suggests that beer was brewed in other ancient civilizations as well, including China, India, and the Americas.

So, rather than a single inventor, it's more accurate to say that beer was a product of collective human ingenuity that evolved over time in various cultures around the world.
