Where is everybody?
twice in one solar system, then we can be relatively sure that the Great Filter is still ahead of that stage of development. Unfortunately, given the challenges we face today with climate change, nuclear weapons, and themany possible extinction events that could hit our planet and wipe us all out, I believe that there is a good chance that the Great Filter is still ahead of us. So, will we find intelligent alien life in our galaxy? I believe there is a good chance we will, but only if we survive long enough for our radio signals to reach them. So all we need to do to find alien life and form a galactic inter-species alliance trading technology and knowledge for the betterment of both parties is to protect the Earth from a whole host of life-ending catastrophes, prevent the collapse of our ecosystem due to man-made climate change, overcome the divisions of the world to become a unified, peaceful civilization, and not kill each other in the meantime.
How hard can it be?
