   I'm slightly more optimistic than you. I believe Mars is reachable and   
   if we limit ourselves to unmanned tech, even Proxima Centauri &   
   beyond. It's even claimed that if we had maintained the funding on   
   nuclear propulsion we might already be there!   
      
   We = unmanned tech   
      
   But there's a temporal divide and not just one of distance.   
      
   Let's say aliens send a probe to investigate the life on earth.   
      
   Great. Life is BILLIONS of years old. So the odds say that it arrived   
   a couple of billion years before we evolved.   
      
   Homo, humans, are only like 2.5 million years old, starting with Homo   
   habilis...   
      
   So if a probe arrives once every million years, there's been two to   
   three since habilis.   
      
   Suddenly our odds of even detecting the debris from an alien probe   
   become ultra slim.
