Bringing an Adamic couple to earth was in accordance with a universal development plan of God. The purpose was to bring about some genetic improvements in the bodies of the naturally evolving tribal peoples of earth who had attained highest levels of material development possible by the controlled natural evolution. This would have been possible when the descendants of the original adamic couple increased in number to about one million on earth in later years and a desired intermarriage between the adamic progeny and the tribal people took place in large numbers.
Had this happened in that manner, the later generations of human beings on earth would have been increasing in population with the adamic genes to such an extent that at some time all people of earth would have been with the adamic genes. This would have created a situation where all people on earth having both efficient physical capacities ( gained from their natural evolution) and efficient mental capacities (gained from the adamic genes). The modern human population on earth, while having the abilities to overcome the hardships of nature would also have the capacities to understand higher spiritual meanings of life and to make their planet a better place to live, by their own efforts and actions. The majority of them would have been in a position to understand and appreciate the plans of God in a better manner. They would have been in a position to live in a material world with a love and appreciation of the spiritual worlds.
But unfortunately, that did not happen on earth in that manner, because of an error committed by the adamic couple who had come to earth for achieving the biologic upliftment of the evolutionary people of earth.
This error later became known on earth as the 'original sin' in the later day stories and religious books of the earth's people. Had this sin not taken place, perhaps earth would have been a better place to live. The earth humans would not have fought among themselves for petty issues arising out of greed, ego, selfishness, ignorance, envy, anger, atheism, theism, in-compassion, laziness, antagonism, and the like.
What was this error ? The original adamic couple who were sent to earth with a mission, instead of waiting patiently for their progeny to grow in number as advised by their superior godly personalities in accordance with the universal laws of God, acted in an undignified manner. Original Eve did an adulterous act. She conceived a child from a tribal earthly man and gave birth to Cain, her first born son from an earthly association. Knowing about this, the original Adam in a kind of retaliatory act, proceeded to take a tribal woman as his second wife who bore him a girl child. From this originated the story of Eve eating the forbidden fruit (apple) first and Adam eating it later. Their acts of first sin !
In getting Eve in to this adulterous liaison with the tribal man, another tribal man played the role of a friendly facilitator. He played the role of a cunning serpent and came to be known as the serpent of the garden of Eden in the later folklore. In all these acts, some super human personalities invisible to human eyes, too played certain facilitating roles. They, though mighty godly beings who were part of the invisible universal administration of God earlier, had erred to foil the universal plans of God in a bid to isolate earth from the the same universal administration of God. And that is yet another story.
The earthly tribal people had been considering Adam and Eve as respectful godly beings superior to them before this incidents happened. But when Eve and Adam acted in this manner, the respect of the tribal people turned to hatred and enmity. Remember, this can happen even today. Certain acts of superior people can hurt the feelings of inferior peoples seriously to the extent that the inferior groups can move in a frenzy to kill the superior ones. In fact, this was the reason for the Godly restrictions for Adam and Eve to show restraints and patience for implementing their mission.
Thus a general kind of enmity and suspicion developed between the existing tribal peoples and the progeny of Adam and Eve in the later years. The intermixing of these races of peoples did not happen the way it should have been.
Our present day scientists and biologists are wondering why the human population have this characteristic difference in their bloods with regard to the Rh factor. Almost 95 % of the human population have the rhesus monkey blood factor (Rh +ve factor) in their blood while the minority fraction has this factor absent in their bloods (the Rh -ve people) Recent genetic mapping studies have proved that the Rh negative factor got in to humans some 35000 years ago. You can see and read reports of this by doing an internet search. Thus, the story I have narrated above should be correct even with the presently available scientific evidences.
If you are a bit logical with a superior mind capacity, it is not difficult for you to understand that the stories of the religious books are not false, after all. But they are written from hearsay folklore that existed thousands of years ago, by people having some superior abilities than their contemporaries. These have gone through many re-writings and re-telling by many over the next few millenniums and many centuries. They constitute our traditional knowledge and our evolutionary knowledge and beliefs.
Since the majority of us do not have gained from the superior genetic factors of the adamic blood, it may pose difficulties for most of us to comprehend certain advanced knowledge that apparently appear as contradictory to our belief systems. That is why our scientists find it difficult to assimilate the spiritual knowledge of our religions and vice versa. That is why we find the general antagonism every where in our present day living that cause much difficulties and hardships to each and every one of us. In reality, our problems are our own creation, either knowingly or unknowingly. If unknowingly, our genetic shortcomings are to be blamed to some extent.
But our world is on a progressive path. The error of the original Adam and Eve had caused a slowdown of our development pace. But yet we are progressing. Had the fault did not take place, our progress would have been the way God had planned for us. The 21st century humans would have been much different than what they are at present. And that difference would have been mainly in our attitudes and outlooks and not in our material progress.
Just imagine what could have been this earth with we possessing all the scientific knowledge and technological abilities while we equally possessed the qualities of love, compassion, love and reverence to God, passion for service, humility, selflessness and such other positive qualities a bit better than we presently have ?
That does not mean that the evolutionary peoples are incapable of acquiring such qualities without the said biologic uplift. It might still be possible if we willfully decide to go in the right path. Had we been biologically upgraded with the adamic genes, perhaps we could have attained a higher civilization on earth much earlier ! A civilization advanced both in material and spiritual prosperity !
