i wathed this program and they कहा that they will be here in 2015 that they had contact but,they dont know that they are already here...do आप think so?

i think i get what your asking. I think that aliens have periodically visited us throughout history (im an ancient astronaut theroist) and with all the sitings that have tooken place I think there is a good chance they r here already.

I believe they're already here.

yep, theyre here, with their cloaking suits, just observing lookig for one who is worthy, and obeys the laws of stone;-]
