Do any of us know when did humans sent their first radio signals to space? I think it was in the mid-70s.(1974). That means there were some species, who sent the signal to Earth 9 billion light years back!

 We are just 4.5 billion years old, this means, either they predicted our birth and the life  sustaining atmosphere in this part of the world then , or they randomly sent some signals, but as per the scientists these were specific signals, we should be aware that what we are dealing with is some super intelligent species who were predicting the birth of a life sustaining planet 5 billion years before our birth !!!! Interesting is in it????
