- Self - Host: What if? What if? What if the alien is real? Let's consider. He was an explorer, perhaps a scientist, crashed and died on a distant blue planet light years from his home. A frightened race of beings found his lifeless body, performed experiments and hid the results. Why did he come to our planet? What went wrong? Obviously his own mission failed. But in his death, he may have delivered the most important message mankind has ever received. We are not alone. I'm Jonathan Frakes, goodnight.
