The first female / Lilith
In the first creation story, God creates "Adam" male and female at the same time in his image. (Note that creation starts with creating opposites: darkness / light, evening / morning, upper waters / lower waters, land / water; but they are endpoints on a scale: evening-morning, sky below clouds-fog, shoreline.)
(כו) וַיֹּ֣אמֶר אֱלֹקִ֔ים נַֽעֲשֶׂ֥ה אָדָ֛ם בְּצַלְמֵ֖נוּ כִּדְמוּתֵ֑נוּ וְיִרְדּוּ֩ בִדְגַ֨ת הַיָּ֜ם וּבְע֣וֹף הַשָּׁמַ֗יִם וּבַבְּהֵמָה֙ וּבְכׇל־הָאָ֔רֶץ וּבְכׇל־הָרֶ֖מֶשׂ הָֽרֹמֵ֥שׂ עַל־הָאָֽרֶץ׃ (כז) וַיִּבְרָ֨א אֱלֹקִ֤ים ׀ אֶת־הָֽאָדָם֙ בְּצַלְמ֔וֹ בְּצֶ֥לֶם אֱלֹקִ֖ים בָּרָ֣א אֹת֑וֹ זָכָ֥ר וּנְקֵבָ֖ה בָּרָ֥א אֹתָֽם׃
(26) And God said, “Let us make humankind in our image, after our likeness. They shall rule the fish of the sea, the birds of the sky, the cattle, the whole earth, and all the creeping things that creep on earth.” (27) And God created humankind in the divine image,
creating it in the image of God—
creating them male and female.
(ז) וַיִּ֩יצֶר֩ ה' אֱלֹקִ֜ים אֶת־הָֽאָדָ֗ם עָפָר֙ מִן־הָ֣אֲדָמָ֔ה וַיִּפַּ֥ח בְּאַפָּ֖יו נִשְׁמַ֣ת חַיִּ֑ים וַֽיְהִ֥י הָֽאָדָ֖ם לְנֶ֥פֶשׁ חַיָּֽה׃ (ח) וַיִּטַּ֞ע ה' אֱלֹקִ֛ים גַּן־בְּעֵ֖דֶן מִקֶּ֑דֶם וַיָּ֣שֶׂם שָׁ֔ם אֶת־הָֽאָדָ֖ם אֲשֶׁ֥ר יָצָֽר׃
(יח) וַיֹּ֙אמֶר֙ ה' אֱלֹקִ֔ים לֹא־ט֛וֹב הֱי֥וֹת הָֽאָדָ֖ם לְבַדּ֑וֹ אֶֽעֱשֶׂה־לּ֥וֹ עֵ֖זֶר כְּנֶגְדּֽוֹ׃
(18) God ה' said, “It is not good for the Human to be alone; I will make a fitting counterpart for him.”
The Alphabet of Ben Sira uses verse 18 as the jumping off point to explain why creating male and female at the same time from the same substance fails miserably. (There are many other Midrashim and Talmud discussions and folk tales about Lilith; e.g.,Shabbat 51b, Rabb/ei Nachman of Breslov's Sichot HaRan 65:1.)
All about Eve
In the second creation story, Adam's side becomes a woman, whom he later names Chava (Eve). She is created to be a "fitting counterpart"; the Hebrew, Ozer C'negdo, could be translated as a helper against or opposite or facing or in front of him.
(כ) וַיִּקְרָ֨א הָֽאָדָ֜ם שֵׁמ֗וֹת לְכׇל־הַבְּהֵמָה֙ וּלְע֣וֹף הַשָּׁמַ֔יִם וּלְכֹ֖ל חַיַּ֣ת הַשָּׂדֶ֑ה וּלְאָדָ֕ם לֹֽא־מָצָ֥א עֵ֖זֶר כְּנֶגְדּֽוֹ׃ (כא) וַיַּפֵּל֩ ה' אֱלֹקִ֧ים ׀ תַּרְדֵּמָ֛ה עַל־הָאָדָ֖ם וַיִּישָׁ֑ן וַיִּקַּ֗ח אַחַת֙ מִצַּלְעֹתָ֔יו וַיִּסְגֹּ֥ר בָּשָׂ֖ר תַּחְתֶּֽנָּה׃ (כב) וַיִּ֩בֶן֩ ה' אֱלֹקִ֧ים ׀ אֶֽת־הַצֵּלָ֛ע אֲשֶׁר־לָקַ֥ח מִן־הָֽאָדָ֖ם לְאִשָּׁ֑ה וַיְבִאֶ֖הָ אֶל־הָֽאָדָֽם׃ (כג) וַיֹּ֘אמֶר֮ הָֽאָדָם֒ זֹ֣את הַפַּ֗עַם עֶ֚צֶם מֵֽעֲצָמַ֔י וּבָשָׂ֖ר מִבְּשָׂרִ֑י לְזֹאת֙ יִקָּרֵ֣א אִשָּׁ֔ה כִּ֥י מֵאִ֖ישׁ לֻֽקְחָה־זֹּֽאת׃ (כד) עַל־כֵּן֙ יַֽעֲזׇב־אִ֔ישׁ אֶת־אָבִ֖יו וְאֶת־אִמּ֑וֹ וְדָבַ֣ק בְּאִשְׁתּ֔וֹ וְהָי֖וּ לְבָשָׂ֥ר אֶחָֽד׃
(20) And the Human gave names to all the cattle and to the birds of the sky and to all the wild beasts; but no fitting counterpart for a human being was found. (21) So God ה' cast a deep sleep upon the Human; and, while he slept, [God] took one of his sides and closed up the flesh at that site. (22) And God ה' fashioned the side that had been taken from the Human into a woman, bringing her to the Human. (23) Then the Human said,
“This one at last
Is bone of my bones
And flesh of my flesh.
This one shall be called Woman,
For from a Human was she taken.” (24) Hence a man leaves his father and mother and clings to his wife, so that they become one flesh.
Eve eats the forbidden fruit, gives some to Adam, they realize they are naked and feel shame, God shows up and is unhappy and tells Eve that from now on her man / husband shall rule over her.
“I will greatly expand
Your hard labor—and your pregnancies;
In hardship shall you bear children.
Yet your urge shall be for your husband,
And he shall rule over you.”
The only time Lilith appears in the Tanach is in Isaiah:
(יד) וּפָגְשׁ֤וּ צִיִּים֙ אֶת־אִיִּ֔ים וְשָׂעִ֖יר עַל־רֵעֵ֣הוּ יִקְרָ֑א אַךְ־שָׁם֙ הִרְגִּ֣יעָה לִּילִ֔ית וּמָצְאָ֥ה לָ֖הּ מָנֽוֹחַ׃
(14) Wildcats shall meet hyenas,
Goat-demons shall greet each other;
There too the lilith shall repose
And find herself a resting place.
Rashi explains:
(ד) לילית. שם שידה:
... (4) lilith The name of a female demon.
