I don't think faith is synonymous with trust, though certainly people use it that way some of the time.

You can deny the reality of any deity, calling all mystical experiences "illusion", because these experiences are dreamlike. The existence of a deity hasn't yet been proved on the gross physical level of ordinary reality. At one time, people denied the reality of bacteria, but in time, we found ways to see and study them.

I think your "simple" position that there is no God is just as much a matter of dogmatic faith as my position that Deity/ies (in one form or another) exists.

think that the only assertion regarding God that is fully supported by logic is "we don't know".
