Imagine a planet having the right conditions to develop life then hundreds of millions or billions of years later it develops intelligent civilizations. Then these civilizations develop advanced technology. Then they send signals into space. And then finally, there is another civilization in another star system that also not only developed life but also intelligent technological civilization to receive those signals at the same time frame as the other civilization. Its honestly like winning the lottery twice. It seems absurdly unlikely that both of these civilizations would existat the same time and be at a technological development to communicate.
