The ONE EXPLANATION is that either nothing or very little on the BC is accurate.Our friend Miriam F. after retirement from a career in the Foreign Service observed about lunch with the king of Nepal and his brother, "They tell you a beautiful story. It isn't the truth, but it is a beautiful story."
In order to know truth (about anything), a person first needs to clear their mind of preconceived debris and take a fresh look at the evidence.
“Dreams” was written to provide a fake life for Zero so he could become President. So nothing in their is believable unless it has corroborating evidence. I wish people would understand that. Many seem to be more or less accepting much of Dreams as the default truth, and only things that have water tight proof of falsity, do they deem false. It should be the other way around. Everything in Dreams is false unless proven true by other means.
