About the scientific thinking and aliens

  1. Aug 11, 2012 #1
    Hello

    I was thinking about how could we think if we arrived to a new planet and found a strange buildings and a complicated machines but we haven't found any living creatures or aliens , just a srange buildings and macheins , could that be an evidence for the existence of aliens ?? we haven't seen any living creature that could be responsible for making that machines and buildings , then what would we say in that case ?

    what could scientists say in that case ??
