Think about this - since mid 2000-2010 we have 1 or 2 billions of smartphone users (and a few hundred millions of older phones with cameras). And those billions of people have been using them for over a decade. Now the question - where are the photos of anything extraterrestrial?

And no, secrecy doesn't apply here really. People manage to take pics of secret military hardware, of terrorist leaders, of practically anything anywhere.
