I know prepping up those atheist guns and firing away is fun to do but you're not really considering the opposite. Would it make sense to be able to see God? the answer is a resounding no.
Unless we're speaking deities specifically, than the very concept of God negates the kind of person-to-person perception and interaction you have (well, hopefully) on a daily basis. You are a tiny little human on a tiny little planet, how you be able to see it?
Try thinking (or answering) about this thought-experiment (to call it that, as you're an atheist). Assume God absolutely objectively exists (in your view), how are you going to see it?
(as I mentioned deities, I am not referring to Yahweh, Jesus, Krishna, Osiris etc here)
