Mars = too cold, and notably, - too light.
Same to the moon
Venus...too hot.
Earth....too wobbly most of the time to support intelligent life. Hasn't been on the radio technologi or Seti level for any time at all, and is on a good road to taking itself down the drain if nature doesn't beat it to it...
We're always speaking very long distances for the calculated chance, - something like thousands of years away....
