Earth is about 4 Billion years old. The Universe is about 13.7 billion years old. Assuming that the life process is the same throughout the universe there has to be civilizations existing well advanced beyond our immagination. Lets say for argument sake, we were one of them. Would you make contact with an earthlike planet? I wouldn't!
