The anomaly to be known as the Nisanian Pentagram. According to scientists the most plausible scientific explanation would seem to be that it is a natural, albeit highly weathered, formation known as a volcanic plug.
Although they say it is a volcanic plug, it looks more like something which is artificially made, it just doesn't fit in the surrounding area.
It also seems impossible that it was a meteor impact, other meteor impacts don't leave craters like this one.
Now Google labelled this anomaly as 'H 666'
666: 6+6+6=18=1+8=9 - 9 is the number present in the universe.
Could it be that a long time ago extraterrestrial visitors have made this pentagram symbol to show the early civilization that the pentagram, the number 9, is the connection to the universe and other worlds?
