We are just too stupid to see them,(reply>), Do you see the failure of the Drake Equation to ignore the mean temperature must be near 0 'C in order to accelerate and balance the cycles of the growth of bacteria and viruses that are essential for life?  This reduces the probability of sustainable life by the offset of mean temperature of the planet for creation of a habitable atmosphere which is extremely thin.  Your numbers are just guesses.,(reply>), Universe age approx. 14 billion earth years. Approx no. of stars: 200 billion trillion.<br>Approx no. of galaxies: 200 billion to 2 trillion.<br>Approx no. of stars per galaxy:<br>100 billion. <br>Approx. no. of planets per star: 1-2<br>Approx. no. of habitable planets per star: 1<br><br>The answer to the equation would be a lot different with these numbers.,(reply>), @Universal Refuge Found I noticed the same issue, and had the same question.  I had never seen the first variable as "new stars per year", rather it tends to be "total number of stars",(reply>), You my friend brother are one of the best ✌️❤️
