Lex,  I know you probably won’t respond I respect your social media limits.  However,  I was listening to a another smart guy.....not this podcast......say we are probably alone.  Don’t let these smart guys say such stupid things.  Push back.  Even if you take our existence and multiply it by the known planets by galaxy x number of Galaxy says there are millions of planets like us and we are not old from a galaxy standpoint.  These genius’ are saying something stupid .
