New model predicts that we're probably the only advanced civilization...

77. Wow, what a bold statement.

The Milky Way Galaxy is believed to be 30,000 Parsecs long and an unknown number of Parsecs wide. From our position in the Orion Arm of the Milky Way Galaxy, we can't see what is on the other side of Sagitarrius A, nor can we see into most of the Galaxy arms that are on our side of Sag A. There are an estimated minimum of around 400 BILLION earth like planets in the known Milky Way, the probability of there being no life on many of those planets is close to zero. The newest stars to us are Proxima A and Proxima B at just over 3.58 light years away (around 19 trillion miles), both have two earth like planets each, one have a potential third one. In order to get to either earth like planet we would need spacecrafts that don't need star power (solar power) or conventional, or expendable fuel, because most of their travel will be in dark space without a chance to refuel. In addition, the spacecraft must be capable of continuous acceleration at 1 G for around a year to even make the trip in about 4-5 years, the energy expenditure for such a feat is beyond what is considered feasible by scientists. So the issue isn't whether there is intelligent live in the MWG, it is whether there is life intelligent enough to figure out how to overcome the technical challenges of reaching other life.

Several time here, I have stated that if alien life reach us, we are screwed if it is hostile to us, by the time we even knew it was here, we would likely be thousands of years less advanced that it is.

Maybe I am wrong, but I get the sense that this OP was done for religious reasons, that is cool, a person believe as a person believe and have reasons for that. But I want to throw something out for you to ponder. If life has reached earth other than us, it is potentially millions of years more advanced than us. What if what religious people call God, was instead an intelligent race that simply left the seeds for us on this planet and moved on. Who do you pray to? I am a Deist, I believe in something more universal that us, but the firm is something that I will spend a lifetime seeking to understand. I don't believe in hell, but I do believe in karma, in karma, our hell comes at consciousness of death being imminent, as in those last seconds we relive our lives, all the good, all the evil, if most was evil, our hell comes in the seconds that life drains out of us, if good, we die with a smile on our faces.
