Okay, let's take the clone theory as to who came first, Adam or Eve?
There are some in the medical community who have posited that the male chromosomes are a mutation of the female chromosomes. One of the X chromosomes mutated and ended up with what we now call the Y chromosome. If you look at the side-by-side picture of the two, the Y certainly looks like a mutation.
Then there is the "we all begin life female" thing until something in the DNA kicks in and mutates one of the X's and turns it into a Y. And the fact we all need at least one X. So X has to be the perfect chromosome and that leaves only Y to be the mutation.
By that line of thinking, Eve had to come first. The Big Guy in the Sky tried to clone Eve. Out came this mutation. If you ever saw the movie
Multiplicity you'll remember how the clones of the Michael Keaton character were all mutations. So that proves this is what happens when you clone somebody.
And now we know. Eve was not trans, nor was she created from Adam's rib. The first human was in fact female. ..........BUT!..........
There is still Lilith. So maybe the Big Guy created two perfect humans. Then he got a little lazy. I mean, he had already done it twice, from scratch.
The thrill was gone. So why not just copy the formula from one of the two and put it in the petri dish and sit back and enjoy the show?
Then this hairy creature emerges, snorting and sniffing, looking for something to have sex with. 
Now the Big Guy was going to destroy the thing but was sort of amused and decided to lock it up and observe it.
Then it escaped... and sniffed out Lilith. It was stronger than Lilith and forced her to have sex. Then, after it got bored, it started looking for some new tail and sniffed out Eve. And it had sex with her.
The Big Guy was pissed! He needed to have a talk with the creature he now called Adam. He told Adam he could live in this paradise, have sex with either Lilith or Eve anytime he wanted (both if he was feeling brave), eat all the food he wanted and if he was good, would soon be able to sit back on a Barcalounger watching sports on a wide screen plasma with all the beer he could drink, served ice cold.
NICE!There was just one condition, Adam had to stay away from one fruit tree.
Just one! The Big Guy just wanted Adam to show him that he knew the Big Guy was still the boss.
But could he do it?
NOOOOOOOOOOOO! 
One day, right after Adam's favorite football team got trounced in the Garden Bowl, Adam, quite drunk from all the Serpent's Ale he drank during the game, started seeing serpents coming out of the can and talking to him. He got up from his Barcalounger, head spinning, and stumbled over to the Forbidden Tree to throw up. He tossed his cookies and right afterwards heard those voices again. And, looking up, there was one of those serpent images looking down at him from the Forbidden Tree.
"Eat this apple dude! It will make you feel better. Then you can go have sex with one of the chicks and you won't even need Viagra!"COOL!Naturally, Adam being your typical Garden of Eden macho dude, took the apple from the Tree but, like the pig he was, swallowed the thing whole.
It got stuck in his throat!
As he lay on the ground, choking to death, he pleaded to the Big Guy to save him. "Big Dude Guy! Please save me!"
The Big Guy said, "I'll save your sorry ass but I'm going to leave you with a reminder that when you disobey me, bad things happen."
Adam said, "Anything Big Guy in the Sky!
ANYTHING!!! I just want to live and watch sports and drink beer and have sex... in that order."
So the Big Guy let him live but left a reminder that all men live with to this day. The Adam's Apple.
And that folks, is the
REAL story.
