Please do not add original research or novel syntheses of published material to articles as you apparently did to Potential cultural impact of extraterrestrial contact. Please cite a reliable source for all of your contributions. ''Please do not add self-published material. Thank you.'' David J Johnson (talk) 11:27, 31 March 2020 (UTC)
