So I think the Genesis 2 account is really neat. Basically, in Genesis 1, God creates the various stuff in the world, and deems it good.
But after God makes Adam out of dirt, he says “It is not good for man to be alone.” So God brings all the animals to Adam, and he names them. But you just get this sense towards the end that he’s kind of getting discouraged, because, in fact no suitable helper could be found!
So God does this crazy thing where he takes part of the dude, and makes it into the dudette. And when God brings the woman to Adam, he’s totally thrilled! This was Very Good!
“This at last is bone of my bones
and flesh of my flesh;
she shall be called Woman,
because she was taken out of Man.”
(Notice how he’s still doing the job God gave him to do, of naming all the creatures.)
So it is, to this day, that we look for our counterpart, the one who is like us, for after all, it is not good to be alone.
