4.Would any extra-terrestrial civilisation be aware of our presence?

Question

options : 1.YES

2.NO

Answer 1

Well, probably not.  

The only way they'd be aware that we're here is by listening to our radio signals or at least seeing our lit-up cities from space.  Those signals and light travel at, well, the speed of light.  The distance that light travels in one year is called a light-year, and the nearest star that isn't our sun is four light-years away.  

http://www.solstation.com/stars/s10ly.ht... which is concerned about this issue, sez that there's a slim possibility that one or another of these close stars has a planet capable of supporting life.

The problem is that there is a far greater chance of some sort of civilization living farther away than that, due to the larger number of stars contained in that larger radius.  But we've only been broadcasting radio signals and bright lights for perhaps the past hundred years, so anyone farther than 100 light-years away won't have heard or seen us yet.  

The light you'll see from the stars in the sky tonight left most of those stars millions of years ago.

Answer 2

Answer 9

3. maybe

Answer 10

Yes...they watching you on answers !!....haha

Answer 11

Our radio signals would be reaching 100 light years approximately; unless they had faster than light travel (or had been here before), no civilisation outside that space could know about us, which makes the probability very low.
