No matter what modern historians would say, when one studies Samhita parts of the Rigveda one gets tempted to believe that ancient Indians were indeed in touch with divine Aliens or the Devas from other worlds.
The dialogues with the Devas are so intimate. The descriptions of the Devas, their vehicles, as well as the way they arrive at the sacrificial place, all look so real. One refuses to believe that they were all part of superstition or the beliefs of primitive men.
