yes,
"one monkey don't make no show"
they also found only one flint and only one bit of beaker pottery but much is being made of that.
and had they found some bit of proof of astronomical or religious use of stonehenge, regardless of how small, much would be made of it.

one grain does not prove my theory but, it does once again imply that
"the grain and the stones are connected."

thanks.
