Yes, I agree (the evidence for a Neolithic connection between Egypt and Britain). However the evidence for many things is flimsy, and that's often what makes it interesting (and entertaining). I've a paper in front of me entitled 'Smoking Mummies' by Mike Haigh in which he discusses the presence of tobacco in the abdominal cavity of the mummified remains of Rameses II - now there's a brain tickler that's hard to resist :-)
