That is very intelligent question, smiddy.
Even in the unguided evolution process there is knowledge: “Life found the best way, through a billion-or-so years worth of experimentation, to keep DNA molecules alive.” (from The Selfish Gene, Richard Dawkins). Further, our DNA molecules seem to have “programmed” us to instinctively know what risks we should take to try to help our genes survive; those that didn’t, didn’t survive!
If such superb knowledge is displayed in the material world, why do God and His only-begotten son require the help of 144000 humans?
But the fact is that 'king priests" concept is originally a Sumerian one.
