All living things are related, in the sense that if you go back enough generations there will be a common ancestor! Just because you need to go back several hundred generations or more to find it doesn't mean it wasn't there, or that it's any less valid a relationship than one animal might have with its sibling. If you go back far enough up the evolutionary tree (say, some point beyond 3 billion years ago), you'll find the single-celled organism that eventually gave rise to both plants and animals!

In a similar sense, the "most recent common ancestor" will be some dude and lady from 50-100 years ago, i.e. your common grandparents. At the very latest, the "most recent common ancestor" you share with anyone on this forum will be a lady running around Africa no more than 200,000 years ago - though with most people you'll share a much more recent ancestor. Keep going back far enough and you'll find a common ancestor with orangutans (14 million years ago), mice (88 million years ago), dinosaurs (about 300 million years ago), and even fungi and plants (somewhere in the billions of years ago)!

Basically taxonomy is super-cool and it's why you can't call a watermelon a rockmelon's bro, but a cucumber can totally fill that position.
