Creation is complex... Love between creatures that are special in species and in foundation, are possible because God can do anything....
"6 And it came to pass, when men began to multiply on the face of the earth and daughters were born unto them,
2 that the sons of God saw the daughters of men, that they were fair; and they took for themselves wives of all whom they chose.
3 And the Lord said, “My Spirit shall not always strive with man, for he also is flesh; yet his days shall be a hundred and twenty years.”
4 There were giants on the earth in those days; and also after that, when the sons of God came in unto the daughters of men and they bore children to them, the same became mighty men who were of old, men of renown."
Holly Bible, St. James21st Century King James Version (KJ21)
Genesis 6, 2-4 ....
There will come a time (says someone...) when mythology will solve our problems... science, the poor child who wants to steal human souls, he will perish, as the scriptures say...
Thank God for the profound truths that emerge from where human malice and ignorance have buried them...
Thanks to the authors for the courage and the ideas transmitted...
