It was Sunday the day of rest and I was lying in bed. Then I started wondering so how did it all begin, have you ever tried working it out. I mean there are plenty of creation myths. Take the Bible. In the beginning, God created the Heaven and the Earth… continuing over the next few days he went on to do other things and then on the seventh he took a rest.
A belief in religious faiths, their promises, it sufficed the needs of my parents, their parents and their parents before them, that already sounds like the Old Testament so-and-so begat so-and-so, and so on apparently indefinitely.
It was similar, I guess across other family groups in the area I was brought up. Of course, dependant on what region of the world you aspire from, or the religious faction to which you were raised, the above explanation or something similar was OK.
Adherence by the populace to religious doctrine kept the priestly elite in comfort for more than a few millenniums. Then the scientist started to turn things on their heads. They caused a bit of bother with the priestly order, and from my reading of history, they still do by all accounts.
