Please do not add your own unsourced speculation to articles as you did at Sphinx water erosion hypothesis. Bring WP:RELIABLE sources to WP:VERIFY all information added. Also, your repeated insertions are a violation of WP:3RR, instead of discussing it at the talk after first removal, and can lead to this IP being blocked.  He  iro 21:30, 9 February 2018 (UTC)
