How does a alien survive on Mars?

Answer:
An alien would presumably not need to breath oxygen as if they have some kind of ESP, they don't even exist.

Edit- i doubt they do exist too but if they did, there's no reason to believe that they would have some special ability like ESP. I wasnt talking about some super alien race, just a creature who can survive and all creatures on earth need oxygen, water, and some form of food. there are trace amounts of oxygen on mars (in the form of iron oxides, unusable by us but might possibly be used by them) but the other two are still missing for an alien to grow and develop unless their chemical compound is that different
