clearly something prevents the development of abundant advanced life that builds interstellar spacecraft. |
Eh? Firstly, there have been quite a few Goldilocks planets found already and secondly, if there are spacefaring aliens out there, why would they visit us anyway and if they did want to visit, how do you know they haven't (ancient alien theory)?
