Spacefaring maybe so. But looking at the numbers for fun I did a quick google to see how many stars there are, there are approximately 100 Billion Trillion stars ( 1,000,000,000,000,000,000,000) Now if there is a 1 in a million chance of any one of those stars having planets that can sustain life that gives us 1,000,000,000,000,000 planets, if you then say that of those there is a 1 in a million chance of any of those planets having life then you get 1,000,000,000 planets with life in the universe. Now you could argue that half are more advanced and half are not, so there could be half a billion of possible spacefaring civilizations. Or if i'm 1 decimal place out 5 billion
OK so the maths is bollox but it does go to show that realistically there is a high chance of space faring life out there in the universe.
