I thought this was put really well.
It's pretty asanine to request 'proof' of the existance of anything on any planet we cannot physically reach. It's not like we have telescopes so damn awesome we can look past the dense atmospheres of many of these planets. Maybe once they establish a moon observatory, but that's at least 30-50 years away.
