My evidence (as I explained above) is the entire field of evolutionary biology and the fact that we are still mammals with the same instinctual drives behind our reproduction.
What's yours, beyond a sense of disgust at the suggestion that you are still just an animal; and a desire to be seen as a paragon of virtue because you had sex and made little versions of yourself?
Been busy, but my god you're a jackass. If you're going to cite evolutionary biology when examining people's motives, you should at least familiarize yourself with the proximate vs. ultimate cause dichotomy. It explains pretty clearly what you seem to be missing about why people have children.
Convincing argument.
