Welcome, Narender.
I'm not sure I understand what you're asking. What factor of Indian mythology do you want us to comment on?
I don't know enough about Indian mythology to make any informed statements about it. But I do know that there's no evidence of any alien visitation.
A lot of people have tried to make one ancient myth or another sound like a description of alien visitation, without a shred of proof. Their reasoning seems to be: "aliens come from the sky, gods (usually) come from the sky".
Hmm, and storms come from the sky, rain falls from the sky, the objects that give light are in the sky. All the things a culture might consider important have to do with the sky.
Another common line of thought for those trying to suggest an alien/gods connection is that primitive people would be in awe of those more powerful than themselves, who could do things that less developed humans couldn't accomplish.
Well, we all grow up as children, surrounded by beings more powerful than ourselves, who inspire awe and sometimes fear, and who can do things we (as children) can't do yet. They're called adults.
So I think there's nothing to the alien visitation idea. Myth alone isn't really proof of anything. If we found something solid, something tangible to suggest that Earth had actually been visited by aliens, then I'd give the concept some consideration. At the moment, however, there's nothing but entertaining stories.
