Scholars have gained knowledge about the Indo-Aryans and their practices through the study of various sources and evidence. Here are some ways in which this information has been established:

Archaeological evidence: Excavations at various sites, such as ancient settlements, burial grounds, and other archaeological sites, have provided insights into the lifestyle and practices of the Indo-Aryans. The discovery of castle remains and related infrastructure, such as fortifications, buildings, and water management systems, indicate their proficiency in construction and land management.

2. Ancient texts and literature: Ancient texts, such as the Rigveda and later Vedic texts, contain important cultural and historical information about the Indo-Aryans. These texts mention practices like the rearing of livestock, including cows for milk production. They also highlight the significance of agriculture in their society, discussing aspects like the cultivation of crops and the use of plows.

3. Linguistic evidence: The study of the Indo-Aryan language family, particularly Sanskrit and its descendants, has provided valuable insights into their daily life and practices. Various words and terms related to agriculture, cattle, and construction found in these languages help reconstruct the Indo-Aryan lifestyle and their dependence on milk and other agricultural activities.

By comparing their practices with other contemporary or related cultures, researchers can trace commonalities and differences, adding to our understanding of the Indo-Aryan way of life.
