Well I believe that our minds are limited in what we can comprehend and perceive. There are just some things we'll probably never wrap our heads around - But if we can think about it in our minds it is probably possible in some way or other. We just may not be able to do it right now - that doesn't necessarily mean it can't be done.

Will we ever understand how and why everything happens the way it does? Probably not but it doesn't stop those things from happening. Hope that makes sense.
