File:Ballearthmath.png

Summary
Was on Commons, deleted per. Image taken from https://eternalworldorder.files.wordpress.com/2016/08/ballearthmath.png. Claim was made in the deletion discussion by the uploader, Steve Engelhardt, that he "helped" make the image, with the signer, Michael Kahnke. That would make him a co-owner, legally able to release the image at least as far as US law is concerned). This is clearly legal to host here unless an owner complains (like almost anything). This file was released under a CC license on Commons and was originally added here from there. A CC license could be claimed from that fact.
