In the Galaxy
Some people should make sure their brain is active before opening their mouths.
Brian Cox is one of these people. A short while ago, he made the claim that humans are the only intelligent life in the galaxy. Now, he claims that Aliens are dead.
Really? He should have stuck to playing music with his band - that is unknown - and left science to people with rational thoughts.
Of course, we're not the only intelligent life in the galaxy; we have no idea how many planets there are in the galaxy, and how many can sustain life. To think that humans are the only intelligent life in the universe is beyond belief and arrogantly puerile.
I'd have put more faith in him if he'd said, "We won't meet aliens because," and then given reasons. I can think of many reasons why we may never meet aliens, but that doesn't mean they don't exist. After all, I've never met a South African but I know there are thousands of South African people.
They could live on planets that need technology to reach that we haven't designed yet as in my story Avenging Angel, like statis pods or time travel. They might not wish to meet us. If they are more advanced than us, they may consider our technology as inferior. Like the Borg in Star Trek, they may wish not to make contact because their species will not benefit.
