ps....perhaps the early humans were so silly that they turned their ceremonial stonehenge site into a mechanical grain mill and took mankind's first step into the mechanical age. and just look where this misstep has taken us, global warming to the point where grain farming may fail us entirely leaving us all back in the stone age. lets hope those aliens return to your landing pad soon and help us out again. tee hee hee.
