Correction: The assumption should be 100 billion. Thus, one percent of this amount is one billion. :)

But our consciousness will let us roughly scan the galaxy by using the power of probabilities. For example, assuming that there are 10 billion planets in the galaxy that are habitable and one percent of these have alien humanoids, then there will be one billion exoplanets that have humanoids in them. Similarly, if you take one billionth of the one billion, then there will be at least one exoplanet with alien humanoids in it. So, the chances are good that the true answer lies in between one and a billion. http://www.huffingtonpost.com/2014/06/24/habitable-planets-seth-shostak_n_5527116.html?ncid=txtlnkusaolp00000592 http://www.huffingtonpost.com/2014/06/24/habitable-planets-seth-shostak_n_5527116.html?ncid=txtlnkusaolp00000592
