This question resolves YES if conclusive evidence is found of any biological life having originated from any other planet. For instance, if dinosaurs or tardigrades are conclusively discovered to have originated from Mars, this question resolves YES. If alien bacterial life is found on other planets conclusively proven not to have originated from Earth, this resolves YES. If by 2100, none of these criteria have been fulfilled, this resolves NO.
