CARET alien writing?

I am interested in anyone’s thoughts on the supposed CARET alien symbols as reported by an “Isaac”.  There are references to this on the Internet and many think this is a hoax.  The reason I post this is that a few years ago, I awoke with a symbol on my forearm (which later disappeared – similar to when you wake up in the morning with pillow lines in your face and they later disappear).  This symbol contained strange “letters” and upon searching the internet for almost a year for similar alien writing, I could find nothing that was similar until I ran across the CARET symbols.  Upon Googling this further tonight, I find that these symbols are controversial and many believe them to be hoaxed.  I want everyone to know that I have no idea about what sort of controvery is going on with the CARET symbols other than I woke up one morning with these symbols on my arm.  So who put them there?  The government?  Aliens?  I want to know which aliens would use this language?  I also posted my query to the Coast to Coast AM radio program (here in the United States hosted by George Noory)  since “Isaac” had been on the show a while back.  I would be curious to see how many other people out there on this site or elsewhere have ever had symbols on their body or run across alien writing (specifically the CARET variety) anywhere?  As far as I am concerned, I believe the CARET symbols to be valid and not something created by “Isaac” (who apparently wishes to be known only by that name – you need to read this stuff on the Internet to get the whole story on who Isaac is and why he wishes to remain anonymous).  Just Google CARET and stuff should come up. Whitley Streiber also believes in the CARET writing, if I am not mistaken.
