Which verses did you read, and which translation? (I suspect Griffith, considering the mentioning of pleas to overpower enemies; something that seems oddly absent from Wilson's translation.)
There's actually several hymns of the Rig Veda that really betray the grand insights that these Sages had that most theists today would shy away from, such as the Nasadiya.

I'm sorry that I cannot recall the translator. I do remember a few curious statements in it, one was reference to the women "and their man," which suggested a polygenous relationship. Indra was one of the gods and mostly there was only one other mentioned in what I read. The men all tempted the two gods with "soma."
My enterpretation of the data about prehistoric Northwest India is that it was invaded by IndoEuropean Kurgan tribes who set up feudal estates as they hunted, herded and spread East across northern India. From the melding of the Kurgan and Tamil cultures, the Hindu religion and civilization developed.
In Indonesia where I lived three years, much of the Hindu culture still survived. I remember the goddess of the Indian Ocean, Ratu Kedal who even Muslims in the region feel that it is dangerous to swim at a beach I went to on the north coast of Java because "She pulled swimmers down into here watery abode."
