There are certain questions that are not just unanswerable but also fathomless. One of those many questions that we as humans have not yet been able to find an answer to or even have been able to gauge the extent of is 'what are the odds of my existence?'
Everybody, at least at some point in their lives have asked themselves this question and have come up with nothing. But then, when you actually sit to evaluate the probability of your existence, you will realize that it all basically comes down to zero.
Why? Well, for one, the probability of your dad meeting your mom, 20 years ago, was actually 1 in 200 million but then he did meet her and the rest as they is ofcourse history.
