The word proofs is used in coins photography and Flat Earth. I don't think Q is talking about coins or photographs. Look at the big clue map and key. The map is the Flat Earth map.

I'm trying to prepare people for the eventual revelation of the truth. The biggest hidden truth that the elites keep from us is the shape of the earth that we live on. This may sound too stupid to even consider. Because 3 short years ago I thought exactly the same way you do right NOW!!! Reading this you probably think I'm a shill or shitposter... Don't get me wrong I do like to shitpost, but this is no shitpost. Question everything. Think big. Think even BIGGER than that!!!!!

Q Anon post # 758 2-14-18 YOU ARE MISSING THE CONNECTIONS!!!!! (((MAP))) provides the KEY!!!! KEY spreads the TRUTH!!!!!! TRUTH shines LIGHT!!! LIGHT saves HUMANITY!!!!!

The "MAP" he's referring to is the United Nations map. The United Nations map is a flat Earth map. They hide the truth in plain sight to mock our stupidity. They put the eye of Lucifer on the back of the $1 bill. They mock the ignorant Goyim AKA cattle!!!!! They think you're a subhuman slave put on this earth to serve them!!!!!
