Eve was a second attempt. Lilith was created at the same time as Adam and was his equal Genesis 1:27-28.
When she dared to ask for some control over when and how she was fruit filled and multiplied she was kicked out of Eden along with her kids!
God then took a rib of Adam's and made the less equal and more controllable Eve Genesis 2:20-23
So Eve had a built in flaw. She was unquestioning obedient not just to God or Adam but any talking snake that happened by...
So the fall wasn't through disobedience but mindless obedience.
Lilith wouldn't have fallen for the trick though she may have tried the fruit out of curiosity?
Wonder where Cain and Seth etc found wives? In those days angels descended to earth from heaven to "know" mortal women and there were already many fallen angels lurking about.
Lilith's kids. Some half sisters, some half Angels and some cute little devils
Pure assumption on my part but I think Lilith was a redhead and Eve a blond!
