hello again wonderful people,
what do you know, a piece of grain was found at the new sh dig. and the video from day 12 talks about the area having been open grassland at the time of stonehenge .

this by no means proves my theory, but it should give us pause. i know there are no converts to my theory among you, but it was very kind of british archaeology to undertake this first dig in 50 years and find a bit of grain for me. perhaps further lab tests on the soil will reveal even more grain residue.
