So,what are your opinions on aliens. Do they exist? Are they visiting Earth? Have they visited Earth in the past? Will we (as a civilization) ever meet them? In our lifetimes? What about less intelligent life?
Personally, I'm a believer that intelligent life does exist somewhere else in the universe. I also think it's faesible they may have visited the earth before, in ancient times. (Quite a reasonable case can be made with stuff like the nazca lines, stone henge, the pyramids, ancient texts and murals etc).
