The trolling response is obvious if you grew up around teenagers playing with this idea:

1. Men developed faster than women.
2. Men started as women in the womb then were able to develop past it.
3. God created a first draft in Adam, then said "i bet I could do it better a 2nd time, and I won't start from scratch this time"
4. There is always a first child when it comes to siblings. "rolls eyes"
5. Well Adam was the first, so there was no bloodlust. Due to eating the fruit, well there was a grudge match scheduled for having the time-out from paradise and introduction of death/bad/good/children - The terms of the grudge match were laid out: fruit of the woman to crush the snake.
