Yes, I had a very positive feeling about that from my childhood, But recently I saw a documentary about the discoveries and research done by people on this topic. I also think that they have already contacted us and they gave us the technology we use in today's world. The artifacts, the monuments, the drawings and the scriptures describing vimaanas, flying saucer type vehicles or chariots coming from the sky.
I am going to write a post on this topic soon.
Looking forward to it.
If they have sense(and I believe they do), they will have minimal contact with general humankind....not to be trusted. I don't.
