[Lucifer] The big questions

A lot of our mortal characters have learned (or let's say are confronted with) the truth about Lucifer being the literal King of Hell, or Amenadiel's position in the Silver City. Why haven't they asked any of the big questions of two beings who know almost literally everything about creation? Do aliens exist? Are the Loch Ness Monster or Sasquatch real? Is Elvis dead? Do ghosts exist? Was Atlantis a myth? Are faeries real? Etc, etc, etc...maybe if Ella ever finds out?

The only two people they could really ask are Lucifer and Amenadiel. 

Amenadiel, despite being thoroughly seduced by life on Earth, would likely refrain from some of those questions out of some sense of duty to the Silver City. 

As for Lucifer, Linda has tried to ask but he's way too selfish and self-serving to pay attention to anything that doesn't directly involved him. So even if he did know about some of those things (which he likely doesn't have the bandwidth to pay attention to in the first place), he would just avoid the question with a "Lets get back to MY problems."
