When Adam and Eve were created, God loved them even more than Lucifer. God loved them as parents love their children, whereas God loved Lucifer as a servant.
God's love for Lucifer was not lessened by the creation of Adam and Eve, but Lucifer felt that God loved him less than before.

Lucifer became jealous of Adam and wanted to hold the same position over him as Lucifer held over the angels. He wanted God to love Adam and Eve through him.
Lucifer could not bring himself to love Adam as God did, but instead felt a jealous hatred toward Adam. At the same time, Lucifer felt a growing impulse of love toward Eve.
God's love is the source of life and power, and the elements of happiness and all ideals. The more loved one receives from God, the more beautiful one becomes. As Adam and Eve were growing toward spiritual maturity, their spirits became more and more beautiful.
Because of Eve's great beauty, Lucifer felt strong love for her. Lucifer did not resist his desire and ventured to seduce Eve, despite his knowledge that this was in direct contradiction to God's will. Ignoring God's command, Eve responded to Lucifer's love. (Gen. 3:1-6)
Through this act of fornication, Lucifer and Eve fell spiritually. By deviating from the Principle, Lucifer left his position and stood against God. Thereupon, he was cast down and became Satan.
One may ask, how could Lucifer, a spiritual entity, have sexual relations with Eve?
When three angels went to Abraham to predict that his wife would have a son, the angels ate a meal with Abraham. By the ford of Jabbok, an angel wrestled with Jacob and dislocated the joint of his thigh. (Gen. 32:25)
When two angels came to Lot to destroy Sodom, the people of the city took notice:
But before they lay down, the men of the city, the men of Sodom, both young and old, all the people to the last man, surrounded the house; and they called to Lot, "Where are the men who came to you tonight? Bring them out to us, that we may know them." Lot went out of the door to the men, shut the door after him, and said, "I beg you, my brothers, do not act so wickedly. Behold, I have two daughters who have not known man; let me bring them out to you, and do to them as you please; only do nothing to these men, for they have come under the shelter of my roof. " (Gen. 19:4-8)
In this context, it is clear that the residents of Sodom were demanding to have carnal knowledge of these angels. In these cases, the angels were thought to be men.
Thus, it is seen that people still in their physical bodies can have contact, including sexual contact, with spirit entities. Spiritual entities possess the same powers of sensual perception as human beings. Indeed, spiritual beings are even more sensitive.
Sexual relationships between spirits and human beings have occurred throughout history. Such a male spirit is called an incubus, and the female counterpart, a succubus. Their invasions are not limited to the past, but even now, occur frequently.
Love unites two beings into one, and through the union, each receives some elements from the other. Having united sexually with Lucifer, Eve received from him the feeling of fear. Lucifer felt fear because of his conscious violation of the Principle, and the same sensation of fear came to Eve.
People today often feel fear without an apparent cause. The presence of evil spirits brings an atmosphere of fear, which people can sense but often are unable to explain.
Evil spirits generate a fear vibration because they are members of the non-principled realm established by Satan in opposition to God. Another element that Eve received from Lucifer was knowledge.
So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate...." (Gen. 3:6)
Lucifer was lower than Adam and Eve in the measure of love from God, but higher in knowledge because he had been created before them.
