Is this too much?

I am grateful for our medical advancements and how much we have learned from studying the world. But have you ever wondered if, perhaps, our body, mind, genetics, universe, religions, and other questions go unanswered because they aren't meant to be answered? Have you ever wondered if they were made so complicated and complex because we aren't meant to figure out what the answers? Are we supposed to just live our lives and be happy and not worry ourselves over these unanswerable questions? There are so many questions that start with "Why" and the best answer that can be given for many of these "Why" questions is just simply "Because"...because that's the way its always been, thats the way it was made, thats just the way it is. Perhaps these questions are better left unanswered.
