How do we know adam had a wife before Ev Does the bible tells us so?
Genesis 1;27 says So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
So who was Adams first wife. Her name was Lilith .
the Jewish story of Lilith has its roots in the anonymous medieval document The Alphabet of Ben-Sira, some interpret the Bible's mention of the wife of Adam in the first creation story (Gen. 1) to refer to Lilith and the Bible's mention of the wife of Adam in the second creation story (Gen. 2) to refer to Eve. Such an interpretation is unsupported by Jewish rabbinic tradition, and can be considered an instance of eisegesis (i.e., reading into Scripture what one wishes to find).
The story of Lilith originally comes from Mesopatamian mythology, in which she is a night demon believed to prey upon children. As the story later became incorporated into Jewish legend, Lilith became the runaway wife of Adam who vowed revenge upon the descendants of Adam and Eve. Out of pious superstition, some Jews, past and present, put amulets around the necks of their children to protect the children from Lilith's murderous designs.
Because legend holds that Lilith refused to be subservient to Adam, she has been adopted by some Jewish feminists as a heroine of religious egalitarianism in modern Judaism.
In another version of the myth of Lilith, she was Adam's first wife before Eve. Adam married her because he became tired of coupling with animals, a common Middle-Eastern herdsmen practice, though the Old Testament declared it a sin (Deuteronomy 27:21). Adam tried to make Lilith lie beneath him during sexual intercourse. Lilith would not meet this demand of male dominance. She cursed Adam and hurried to her home by the Red Sea.
Chapter 10: Adam's Helpmeets
(Excerpt from The Hebrew Myths by Robert Graves and Raphael Patai (New York: Doubleday, 1964), pp 65-69.)
(a) Having decided to give Adam a helpmeet lest he should be alone of his kind, God put him into a deep sleep, removed one of his ribs, formed it into a woman, and closed up the wound, Adam awoke and said: 'This being shall be named "Woman", because she has been taken out o f man. A man and a woman shall be one flesh.' The title he gave her was Eve, 'the Mother of All Living''. 
(b) Some say that God created man and woman in His own image on the Sixth Day, giving them charge over the world;  but that Eve did not yet exist. Now, God had set Adam to name every beast, bird and other living thing. When they passed before him in pairs, male and female, Adam-being already like a twenty-year-old man-felt jealous of their loves, and though he tried coupling with each female in turn, found no satisfaction in the act. He therefore cried: 'Every creature but I has a proper matel', and prayed God would remedy this injustice. 
(c) God then formed Lilith, the first woman, just as He had formed Adam, except that He used filth and sediment instead of pure dust. From Adam's union with this demoness, and with another like her named Naamah, Tubal Cain's sister, sprang Asmodeus and innumerable demons that still plague mankind. Many generations later, Lilith and Naamah came to Solomon's judgement seat, disguised as harlots of Jerusalem'. 
(d) Adam and Lilith never found peace together; for when he wished to lie with her, she took offence at the recumbent posture he demanded. 'Why must I lie beneath you?' she asked. 'I also was made from dust, and am therefore your equal.' Because Adam tried to compel her obedience by force, Lilith, in a rage, uttered the magic name of God, rose into the air and left him.
Adam complained to God: 'I have been deserted by my helpmeet' God at once sent the angels Senoy, Sansenoy and Semangelof to fetch Lilith back. They found her beside the Red Sea, a region abounding in lascivious demons, to whom she bore lilim at the rate of more than one hundred a day. 'Return to Adam without delay,' the angels said, 'or we will drown you!' Lilith asked: 'How can I return to Adam and live like an honest housewife, after my stay beside the Red Sea?? 'It will be death to refuse!' they answered. 'How can I die,' Lilith asked again, 'when God has ordered me to take charge of all newborn children: boys up to the eighth day of life, that of circumcision; girls up to the twentieth day. None the less, if ever I see your three names or likenesses displayed in an amulet above a newborn child, I promise to spare it.' To this they agreed; but God punished Lilith by making one hundred of her demon children perish daily;  and if she could not destroy a human infant, because of the angelic amulet, she would spitefully turn against her own. 
(e) Some say that Lilith ruled as queen in Zmargad, and again in Sheba; and was the demoness who destroyed job's sons.  Yet she escaped the curse of death which overtook Adam, since they had parted long before the Fall. Lilith and Naamah not only strangle infants but also seduce dreaming men, any one of whom, sleeping alone, may become their victim. 
(f) Undismayed by His failure to give Adam a suitable helpmeet, God tried again, and let him watch while he built up a woman's anatomy: using bones, tissues, muscles, blood and glandular secretions, then covering the whole with skin and adding tufts of hair in places. The sight caused Adam such disgust that even when this woman, the First Eve, stood there in her full beauty, he felt an invincible repugnance. God knew that He had failed once more, and took the First Eve away. Where she went, nobody knows for certain. 
(g) God tried a third time, and acted more circumspectly. Having taken a rib from Adam's side in his sleep, He formed it into a woman; then plaited her hair and adorned her, like a bride, with twenty-four pieces of jewellery, before waking him. Adam was entranced. 
(h) Some say that God created Eve not from Adam's rib, but from a tail ending in a sting which had been part of his body. God cut this off, and the stump-now a useless coccyx-is still carried by Adam's descendants. 
(i) Others say that God's original thought had been to create two human beings, male and female; but instead He designed a single one with a male face looking forward, and a female face looking back. Again He changed His mind, removed Adam's backward-looking face, and built a woman's body for it. 
(j) Still others hold that Adam was originally created as an androgyne of male and female bodies joined back to back. Since this posture made locomotion difficult, and conversation awkward, God divided the androgyne and gave each half a new rear. These separate beings He placed in Eden, forbidding them to couple. 
Or maybe this is what happened to Lilith ,A female demon of the night who supposedly flies around searching for newborn children either to kidnap or strangle them. Also, she sleeps with men to seduce them into propagating demon sons. Legends told about Lilith are ancient. The rabbinical myths of Lilith being Adam's first wife seem to relate to the Sumero-Babylonian Goddess Belit-ili, or Belili. To the Canaanites, Lilith was Baalat, the "Divine Lady." On a tablet from Ur, ca. 2000 BCE, she was addressed as Lillake.
There is only one verse in the Hebrew Bible, Isaiah 34:14, that may be a reference to Lilith.
The desert creatures will meet with the wolves,
The hairy goat also will cry to its kind;
Yes, the night monster will settle there
And will find herself a resting place.
So depending on what you believe Could Adam have had a first wife that was removed from the Bible for various reasons. Or like the article suggests did God change his mind .
