Lolz what ground breaking work, pretty much every single star out there is believed to have about 10 plus planets if you include major moons like europa titan luna, and Io. Odds are that there loads of life in the galaxy, anyone that denies this is delusional at this point.
the problem with simpletons like yourself is that you fail to recognise that this isnt a statistical probability based on habitable zones alone. the other dimension is time.
so not only does life have to find a habitable zone, it also has to have had a load of other situations occur to it, AND- this is the biggie- life has to be there when we look. Since we look at the minutest piece of the timescale, the probability of finding life when we look is virtually zero.
the drake equation is still the best way to go and it shows that finding life- intelligent life- is still almost nothing.
the best way to describe it is with the paradigm that when something is infinitely large, it is at the same time, infinitely small. that is what our universe is, to us, until proven otherwise.
so i guess the best minds on the planet must be delusional?
