Re: Just shows how special we all are...
About 11 billion planets in this galaxy meet the first four of your conditions. Add in red dwarfs and we are up to 40 billion. I do not even have a figure for moons of gas giants with a reasonable chance of having had surface water for billions of years.
Multiply that by at least 100 billion galaxies in the observable universe and life becomes something we should expect (although possibly too far apart to stand a reasonable chance of contact).
We have a limited supply of planets for counting large moons, but if you look at trans-Neptunian objects, large moons are quite popular.
Sure there a lot of planets, but if you filter out those that are to larger/small, wrong location, do not have molton cores or the parent suns are to violent, that number comes down a lot.
Is a red dwarf a good candidate for complex life? Firstly the habitable zone would be a lot closer so the planets would be tidally locked, meaning an atmosphere is unlikely to survive. Also Dwarfs tend to be highly variable in output
Is a large gas giant moon suitable for complex life? They tend to suffer from bombardment of other bodies due to the pull of the main body and again get tidally locked.
I have no doubt that there is simple life somewhere else in our galaxy and complex life somewhere else in the universe. However the chances of complex life being around in our galaxy, at this point in time, never mind being detectable seems highly improbable
