在遥远的历史时期，人类首次接触到牛奶，这一发现对后来的农业革命和食物生产产生了深远的影响。关于牛奶起源于哪个国家的问题，其实是一个多维度的探讨问题，它不仅涉及到地理位置，还需要考虑文化传播、经济发展以及技术进步等多种因素。

从历史记载来看，人 earliest known use of milk dates back to the Neolithic period, roughly between 7000 and 4000 BCE. This was a time when humans transitioned from a nomadic, hunter-gatherer lifestyle to one that was more sedentary and agricultural. The discovery of domesticated animals such as sheep, goats and cattle marked the beginning of a new era in human history.

It is widely accepted that the Fertile Crescent, which includes modern-day Iraq, Syria, Lebanon, Jordan, Israel and parts of Turkey and Egypt, was home to some of the earliest farmers who domesticated animals for their milk. The evidence suggests that these early farmers were able to harness the nutritional benefits of milk by developing techniques for processing it into cheese or butter.

The first evidence of dairy farming comes from around 7,000 years ago in ancient Turkey's Çayönü site. Archaeologists have found pottery fragments with residues containing lipids similar to those found in milk fat molecules. These findings indicate that people were already consuming dairy products at this point.

However, it is important not to overlook other regions where agriculture developed independently around the same time frame - Africa's Sahel region (e.g., Mali), South Asia (e.g., Pakistan) or East Asia (e.g., China). While we may not know exactly which country "invented" dairy farming per se; it is clear that many civilizations across different continents independently discovered its value as an energy source.

In conclusion while we cannot pinpoint one single country as being solely responsible for originating dairy consumption due to historical complexities involving multiple cultures' independent development within different geographical contexts; however there are strong indications suggesting ancient Turkey played an integral role alongside other regions like Middle East during this process. As our understanding evolves further through continued archaeological research so too will our knowledge about humanity's journey towards mastering this valuable resource - Milk!
