Epochalyptik is correct. Here is the relevant passage from the Comprehensive Rulebook:
114.9. Spells and abilities can affect objects and players they don't target. In general, those objects and players arent chosen until the spell or ability resolves. See rule 608, "Resolving Spells and Abilities."
114.9a Just because an object or player is being affected by a spell or ability doesn't make that object or player a target of that spell or ability. Unless that object or player is identified by the word "target" in the text of that spell or ability, or the rule for that keyword ability, it's not a target.
