Trying to make sense of why or why not an advanced species that has mastered space and time, would want to do something so pointless as visiting planet earth, is the weakest argument one can make against this. Just because you cannot understand their motives, and it sound implausible, hence it cannot be true, is like a caveman trying to understand why modern humans stare at flat luminicent screens while tapping and clicking away randomly in front of it for hours.
No, totally incorrect. It's not the visitation that is pointless. It's the lack of any "actual" visitation. But it's worse than that. It's like "open secret" visitation. You can play your "One cannot divine the mind of God" game all you want but your argument is still ridiculous. No one said coming to Earth in itself is ridiculous, but it's this whole other game you want to play with it that is just too much.
