Maybe said race has mapped its entire corner of the galaxy? Maybe they possess knowledge we do not. Once again the ego of humanity shows through. Too many variables to make your conclusion. Mathematics is not the end all be all. Sadly to our tiny minds it seems to be.

Just been watching a universe show, they read out some stats:
In our galaxy alone there are an estimated 5,000,000,000 thats 5 BILLION other planets, 1% of these are thought to be in the 'goldilocks' zone of the sun, the area where its not to hot not to cold, liquid water and a strong atmosphere can exist. Only 1% you say? Thats still 500,000,000 planets that have potential to harbour life.
Our neighbour galaxy andromeda, which is BIGGER than our galaxy so lets do some reslistic guess work and say it could have 8 Billion planets, 1% would be 800,000,000 with potential to harbour life.
So in these two galaxys alone lets just round up the total and say there are 1,000,000,000 planets that habe potential to harbour life.
Ok lets add to that, that the Hubble telescope in early 2000s had observed 3,000 visible galaxys, so lets just say as a speculative average that each galaxy will have 500,000,000 potential earth type planets. Lets do the math 500,000,000 multiply it by 3000, thats 1,500,000,000,000. Yep one and a half TRILLION potential earth like planets.
Ok, so thats just the observed universe, now scientists speculate here could be 150,000,000,000 galaxys in the wide universe. Ok so assuming each galaxy has 500,000,000 earth like planets, we now multiply 500,000,000 by 150,000,000,000..................... haha yea right I'll let you guys do that one.
So anyone else still think were the only life in the universe!!!??
In the 60s we get to the moon, then we make it to mars, the discovery of our first earth like planet in the habitable zone is followed by that probe making it to the far outer reaches of the solar system. All that in 50 years, who knows maybe in the next 50 years we will discover how to travel at super high speeds through space and visit that earth like planet.

Another problem I have is the argument that conditions must be perfect. Much like our own. And truth be told that is nothing more than a guess. Just because a planet is tidally locked to its star, or a little closer and hotter, or its atmosphere mainly being methane instead of carbon dioxide does not mean life of SOME form could not evolve and flourish there. Once again that is another problem that stems from our limited knowledge of the Universe and Astrobiology. We cling too tightly to our preconceived notion of life and how it can form. Instead of thinking outside the box and asking questions that are deemed Impossibility or just plain craziness we prefer to stagnate until some discovery smacks science in the face and forces their hand.
I love science and all the knowledge it brings. I hate how it is empirically controlled and anyone who proposes theories that don't jive with the mainstream are labeled quacks or kooks and shunned from the tightknit circles that make up the majority of mainstream scientists. People with supposedly outlandish theories are labeled New Age charlatans etc. It really hinders advancement of our species when new ideas are simply discarded because science refuses to possibly have to change their deep seeded "Truths".
