"Truth" isn't a thing...
Existence is NOT a predicate (quality). However, everything that actually exists does have at minimum one other predicate than mere existence, that can be potentially observed. So far, nothing of the kind has been demonstrated for any version of god that I've heard of.Is existence a quality?
There have been quite a number of anecdotal reasons to suppose there is a god (actually, there has been an absolutely immense amount of this anecdotal stuff -- usually referred to as Scripture), but not a single, verifiable piece of it is actually on offer.
Show me -- in the real world, here and now -- just one thing, a single thing, that can ONLY be explained by the existence of God, and trust me, you will have my attention. I don't think you can do it.
