Same as the odds of every other child that was ever conceived. It's really easy to look backwards in time, think of every single "if this never happened..." moment, and conclude that the probability is near zero. And you would be right.
exactly. think about your existence. You wouldn't exist if your parents hadn't met and reproduced, and if their parents hadn't met and reproduced, and so on until you get to our monocellular ancestor. Everyone here is the product of a very long, unbroken line of ancestry spanning back billions of years! If any of those ancestors had not chosen to reproduce, you don't exist. It's mindblowing to me. Actually one of the main reasons I wanted children was to continue this line, why should I be the one to break it?
For most of human history, spouses probably met from a fairly limited pool of suitors in their small band or village. Of course it became different in large cities, or once international travel became possible, and especially now when you can "meet" someone on the other side of the world without leaving your mom's basement.
