How would I know? I was only pointing out that it may be dated, it may even be too advanced for them....or they do not use the same kind of communication systems as us, so it would be useless.....there may just be plants, or insects on there, or fish or dinosaurs, apes or dogs, anything but human.....hence until we keep trying with other forms of communications we may just be wasting an awful lot of billions.
The system we are using is man made, so unless they have the same mindset as us, its useless.
The only way we will really know is by landing on one of them,,,,but that is still a long way off.
First of all - SETI arent spending "billions" (not even close)..... they are financed entirely by private contributions.
Second - The money and effort are so small with respect to the "pay-off"..... if they would find something.
