I once saw a study that concluded heterosexual couples were more likely to have children than homosexual couples.<p>I mean, there&#x27;s the things we know, and then there&#x27;s the things that have been scientifically studied and validated.<p>And then there&#x27;s the things that really don&#x27;t need to be validated.<p>I once had someone claim that if you drove a vehicle through mud, it would get muddy.  But since it hasn&#x27;t been scientifically proven and validated, do I <i>really</i> &quot;know&quot; that to be true?<p>Is this really going to be an existential crisis where we don&#x27;t really know anything until science tells us it&#x27;s true?
