Actually, God created Adam and Lilith, then killed Lilith off-stage, THEN created Eve. Support for this Jewish folk belief is found in Genesis.

in Genesis 1:27, on the Sixth Day,

So God created man in his own image, in the image of God created he him; male and female created he them.

Then, in Genesis 2:20-2:22,

And Adam gave names to all cattle, and to the fowl of the air, and to every beast of the field; but for Adam there was not found an help meet for him.

And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;

And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.

So, uh, what happened to the first woman?

Then, of course, when Cain left his homeland for the land of Nod he found MORE people, obviously not his brothers and sisters since he marries one of them, so God must have made them too.

So God might well have made Steve as well as Adam!
