It amuses me when scientists say aliens need the same living conditions as we do.  Every living thing on this planet has evolved to suit the environment so who is to say that other beings couldn't evolve in totally different living conditions.  Like inhale argon exhale helium etc.
As far as aliens dominating us for being inferior beings I am not convinced. It is true that we used to do this thousands of years ago but as time has progressed we have discovered many ways of settling disputes without war, although not always.  The more advanced we become the more diplomat and civilized in my opinion, I'm sure that aliens with technology to travel billions of miles would have to be far more civilized than us and probably have very little material interest.

In todays day and age, with so much media around it just isn't conceivable that people with ESP could go un noticed.  "Psychic" abilities in the sense of being able to read minds and predict the future are of course fiction. If anyone is familiar with Derren Brown they will know how these super human tricks are done. He often uses such "powers" quite effectively but unlike other people he reveals how he does it more often than not. Also when it comes to mediums his attitude is similar to that of Houdini because they both know how these fraudsters work.
