It could be possibly, that on the other side of wherever we are, if there is a parallel to us and our existence, I'm not talking about another side of a big universe, but another side to what life, existence and creation is. Like we know that we are humans, we have the power to create, kill and even pollute our world, even though we are smaller than the planet, that there could be something so different. We consist of birth, life, emotions and death, and then what? That is it, that's our existence in this universe. Wow, This stuff really blows my mind I can't even think of anything else, what I'm trying to say is that a parallel to existence, and (if you're the religous type) something different than a creator. It's really amazing stuff to get your brain blown.

And it's true we only know as much as we know, we know nothing at all about this.
