If i was a NASA scientist discussing the fase with someone who thinks it was created by aliens i would tell them that the face was not mad by aliens because it could of bin made by dust and wind or a deid person from milions of years ago also it can be a rock formed as a face .

first i think that the face could of ben made up of dust and wind along time ago because we do not know what was in mars for a long period of time untill we invented satelights, rocket ships and space shutls next i say it could of also ben a deid person. one of the resons i say this is because in space a deid bode can not row or reprodus .

last but not lest a rock could of den formed or a medeor crash thes are some of the things why i think it could not be aliens.
