text: Many weird, unique, creative landforms are found around Earth that weren't human made, so just because there is a unique landform on Mars we believe aliens formed the landfrom? I believe scientists and other people this to start rumors or just want everyone to believe people say this to get a rise out of every one else. Also, I think they just want it to be big news, "Aliens are real and we have evidence!" or something that will get a rise out of everyone.
