Yes but see, the same uncertainty also goes to you. Evidence may paint a picture, but evidence is also continuously fluid so there is never a correct picture. A more accurate picture, possibly. But even so, we're not just ruled by rational thinking. Even scientists are driven by a thing called wonder and curiosity - you need those facilities together to make progress. Call intuition as one tool to take advantage of.
But hey I may be wrong too. There's no telling unless He says "Game's up, now who amongst you could see me." I admit that there is that fear in me, but as I explained in another child post, I just can't put down the super complexity and beauty of this world to a chance.
(If my tone seems condescending, I apologise as this is not in my intention at all.)
