If you could ask one question about anything & have it answered in absolute truth, what would it be?

Instead of all these annoying bodily excretions, why can't our body just recycle them?

I would like to ask - what happens to our spirit, when we die and leave this world.

Is the color orange called that because it's the color of the fruit of the same name, or was the fruit called orange because that's its color? Which came first, the color or the fruit? j/k I would probably ask if there is there another place in the universe out there anywhere that has a life force like earth (plants,animals, societies etc....) or are we just an anomaly?

Seriously, I would ask what do you mean and feel? I think of this when I think of honesty. Do people really tell you, can they explain it and if they can, will you understand. It is like trying to understand what a person feels like who had their child killed when you still have yours healthy and happy or maybe not have a child. How can you really understand? So yeah, explain to me how you feel.
