Neo kinda has the same thoughts I do i that regard then. There's SO much of space we haven't been able to explore (possibly an infinite realm.....which sounds familiar). Imagine space as like the mind. It could leads to literally infinite possibilities. We just haven't learned how to open up that path yet and maybe for good reason. There's many mysteries in this world alone we don't have explanations to. At times (as I do believe in God) I believe that everything that came into existence "here" was created for a reason, fiction or not. It may not exist here, but does that change the fact or may not exist elsewhere?

A planet that's filled with water, a planet filled with volcanic rocks and lava, a planet that matches ours in more ways that one, or even a planet with what we call "fictional creatures." Space is literally as limitless as the human mind with no answers in sight within the near future. So in THAT unknown speaking, it's something that always has me curious what we can expect to learn from it in our future. None of this stuff may exist in what we call "our" world or our "reality," but that may not mean it doesn't exist in some other dimension or part of the unexplored universe.

Other than that, the only mysteries that worry me is pain or medical issues that may pop up (like mystery viruses that have no explanation).
