   Over hype of findings in news articles is commonly discussed here.  They   
   are looking for evidence of life where they expect to find it.  There is   
   already evidence that life existed at that time.  They aren't just   
   making junk up to claim that life existed in those rocks.  They are   
   looking for chemical signatures that life leaves behind in the   
   sedimentary layers that become rock.  Your objection to the over hype is   
   noted, but your objection doesn't change the reality that you can't   
   accept.  As I noted there is other evidence of fossil stromatolites over   
   3.4 billion years old.  You know that you have an objection to that   
   reality, but your issue with this study doesn't matter about what you   
   can't accept.   
      
   You claim to be some type of YEC.  YEC is still are the largest portion   
   of creationist support for the ID creationist scam.  YEC have likely   
   been the victims of all the bait and switch ploys that the ID perps have   
   had to run.  The ID perps sell the ID scam, but only give the rubes a   
   stupid obfuscation and denial switch scam that they tell the rubes has   
   nothing to do with creationism nor ID.  The last bait and switch went   
   down on the West Virginia legislature, and even after the bait and   
   switch had gone down and the legislator had, had to remove mentioning ID   
   from the legislation and replace it with switch scam language, she still   
   claimed that ID could be taught in the West Virginia public schools, and   
   had to have the bait and switch run on her again.

   This is the Educator's briefing packet where the ID perps claim that the   
   Kitzmiller decision was wrong, and that even though ID was found to be   
   illegal to teach in Dover that it is still legal to teach the junk   
   elsewhere.   
      
   The Bait and Switch goes down every single time that YEC creationists   
   want to teach the junk in the public schools.  Most of the ID perps are
