Why doesn't God make his existence too obvious to ignore?

If we are required to believe in and worship God, why doesn’t He make His presence undeniable? Seems like a reasonable proposition. You require worship and belief, make your presence beyond doubt.

I’ll deal with two possible replies and get them out of the way now so we can deal with the others and not waste time on ones that don’t answer the question.

First, He is not beyond doubt. Nobody doubts obvious things. Nobody denies the existence of the Sun,the moon, gravity, inertia,etc. Obvious things are…....obvious. Since many people don’t believe in God on the basis there is no proof, to claim that He is obvious beyond doubt is silly.

Second,the appeal to nature.The “just look at a flowers or the stars” argument. Evolution has shown that these things evolved into being. Whether or not God is the spark at the very beginning is irrelevant to this question, since the question is the obviousness of God. God starting the spark that created the universe billions of years ago is not making Himself obvious today.

Why need faith that God exists? Why not solid evidence that precludes needing faith in things unseen?
