There are many instances in the great epic Mahabharata, which give proof of the presence of aliens in the great battle:
"But asthat car of costly metals was in the sky (alien UFO), full two miles off, it could not, O Bharata, be seen by my troops. They could therefore only remaining on the field of battle look on like spectators in a place of amusement, cheering me on by shouts loud as the roar of the lion, and also by the sound of their clapping. And the tinted arrows (missiles) shot by the fore-part of hand penetrated into the bodies of the Danavas like biting insects. And then arose cries in the car of precious metals (UFO) from those that were dying of wounds by those sharp arrows and falling into the waters of the mighty ocean. And the Danavas deprived of their arms, necks, and wearing the form of Kavandhas, fell, sending up tremendous roars. And as they fell they were devoured by animals living in the waters of the ocean." -- Vasudeva, Mahabharata, Book III: Vana Parva, Section XX, 8th century B.C."And, O perpetuator of the Kuru race, I could not then see the car of costly metals (UFO), for it had vanished, through illusion! I was then filled with wonder! That host of Danavas then, O Bharata, of frightful visages and hair, set up a loud howl while I was waiting for it. In that fierce battle. I then, with the object of destroying them, fixed on my bow-string the weapon capable of piercing the foes if but his sound was inaudible. Upon this, their shouts ceased. But those Danavas that had sent up that shout were all slain by those shafts of mine blazing as the Sun himself, and capable of striking at the perception of sound alone. And after the shout had ceased at one place, O mighty king, another yell proceeded from another quarter. Thitherto also I sent my shafts. In this way, O Bharata, the Asuras began to send up yells in all the ten quarters above and across. These were all slain by me, viz., those that were in the skies and that were invisible, with arrows of diverse forms, and celestial weapons inspired with mantras. Then, O hero, that car of precious metals (UFO) capable of going anywhere at will, bewildering my eyes, reappeared at Pragjyotisha!" -- Vasudeva, Mahabharata, Book III: Vana Parva, Section XXII, 8th century B.C.
