If there’s only one habitable planet per million stars life is uncomprehendingly everywhere. That would be thousands of habitable planets per galaxy.  Times that by 2,000,000,000,000  and you get the approximate number of planets that have life.  Just a few quadrillion habitable planets.  If 1/1000 of those can evolve intelligent life there’s still trillions of planets with intelligent life.  So there’s that.  I would guess that life is much more prevalent than this.  Probably 10-100x... Just want to be conservative to show how much life is probable in our universe.  Again to summarize if there’s only one planet per one million stars with life there are a few quadrillion planets with life. It’s a number that is impossible to fully comprehend.  <br><br>We (the best scientists) don’t even know if our next nearest stars planet has life... So it might be a while or never before we verifiably find life.<br>Update: scientists estimate that there are billions of planets in a stars habitable zone just in our galaxy.   if only 1/100 had life there’s millions in our galaxy times 2 trillion galaxies..  so just a few hundred thousand quadrillions.  Now think of just 1000 of those," and that you could visit one per week.  This would take you over 20 years.  It’s just so hard to imagine how insane some numbers really are.  Good luck.
