The one reason ive never believed in UFOs is because if there are the amount of them we are told - we are already under attack. They are all over us like a wet shirt!

And why dont amateur and professional astronomers spot them first? They are looking into the sky all the time through instruments. This multitude of UFOs would be passing their field of vision all the time. And theres no way they cpould all keep quiet all at the same time in a huge conspiracy.

Though that desont mean there isnt alien life in the universe.

Are there any good new theories in science which answer the fermi paradox? Ive heard the ones like the "zoo theory" which is pretty fun. I keep shouting "get me out of here!" :-)
