Rule 608.3a
Official source text from the 14 June 2019 Rules release
If the object that’s resolving is an Aura spell, its resolution involves two steps. First, it checks whether the target specified by its enchant ability is still legal, as described in rule 608.2b. (See rule 702.5, “Enchant.”) If so, the spell card becomes a permanent and is put onto the battlefield under the control of the spell’s controller attached to the object it was targeting.
