A crystal could be described as an ordered system. Do you believe that some form a deity is involved in their creation?
Look beyond the crystal to the atomic level.
If the atoms were designed to behave in a particular way at certain temperatures, it in no way disallows a creative intelligence behind the formation of the crystal.
Besides, the crystal is magnitudes of order simpler than DNA and does not contain information.
And still the precedent is intelligence, in that when we see ordered systems and know the cause for sure, it’s intelligent. Otherwise, the best we can say is that we don’t know if there was intelligence involved.
There’s no way to say definitively that there wasn’t intelligence involved, because we’ve found no way of determining that. It’s merely a philosophical conclusion that is assuming the conclusion.
