Do Atheists Believe in Soul Mates?

I find the concept of soul mates a little far-fetched.  After all, there are over 8 billion people in the world right now.  If there is one perfect fit for each person, the odds of finding that specific individual is infinitesimal, because geographically speaking that person could be anywhere.  It's also statistically likely that any two given soul mates can't speak the same language.

If soul mates exist, the most likely demographic to find their one and only would be citizens of India.  Their population is about 1.5 billion, meaning at least they have just under a 20% chance of their perfect match living in the same country.  By way of comparison, citizens of Monaco, a country with a population of about 40,000, stand less than a hundred thousandth of a percent chance of living in the same country as that special someone.  Specifically they have a 0.000005 percent chance of living in the same country as their soul mate.

Mathematically speaking, this means that if soul mates exist, either you're almost guaranteed to never find your soul mate, or some external factor would need to exist that guides one to the right individual, at the proper time, in the correct place. Anecdotally speaking, this external factor would need to possess some form of awareness, otherwise it would be unable to identify the correct pair before bringing them together.

This, of course, brings me back to my basic question.  Do atheists believe in soul mates?
