I found it interesting that limestone has been a big element in most ET related phenomenon. For example, the pyramids are made of limestone, crop circles are almost always formed in limestone/chalk rich areas, paranormal activity is usually prevelent in areas where limestone is rich...

what is the limestone connection? what is it about this material that is so important?

England is limestone rich, a site of many crop circle communication.

Areas in America where crop circles are formed are limestone rich.

I wonder if the tablets of the ten commandments were made of limestone?
