Scientists just have faith that Dark Energy exists.  Just how they had faith that certain elements on the periodic table existed before anyone was able to recreate them in a labratory setting.

I know this was a while ago, but faith is not the right word here.  The right word would probably be theory.  They have a theory that dark energy exists.
