No, I have no proof. Religion just seems a simpler and "saner" solution to deal with the origin of the first physical particles, the infinite cosmos and the concept of self-awareness and biologically unexplainable things like species-extrinsic (non-intraspecific) compassion than trying to stick to mere senses, sporadic calculations, scientific (often subjectively orientated and qualitative) studies and quantitative measurements made during the last couple hundred years of human history.Oh really, and do you have any peer reviewed proof that Hippopotamus of Rome was compos mentis at the time and not allowing his scribe Biggus Dikkus to wing it ?
In my opinion what was copied to Christian Christmas (from the pagan Yule/midwinter festival) was a continuum of social habits, customs and decorations. Moreover, it goes both ways (in terms of habits and customs). Nobody knows what kinds of habits and belief systems existed earlier than in known historical records (which were mostly written or artistically supervised by sporadic patricians). Now they are interpreted by competing scholars and common men alike. I think it's nice that we're not a bunch of YES-men or YES-women but individuals .
