Pls asap! what information about ancient india have scholars learned from the vedas?

“The Vedas are the earliest and very influential religious texts of classical India. The Rig Veda is the earliest of the four collections of the songs and other holy texts known as Vedas. These works are regarded as "divine knowledge" of the Aryans who attacked India in about 1600 B.c

Historians considered Vedas as an essential source of information because they assisted in studying the classical civilizations of India and the nature of the administrations and also helped in understanding administration.

Vedas cannot be considered authentic according to me because the actual origin of the Vedas is hidden. Many testimonies imply that they were reproduced by Brahmin priests between 1500 and 1200 B.C, though the ethnic religion of Brahmin priests and the thoughts they wrote continued to be the mystery.”
