Area 51- Real (thats a fact)
Other life forms in the Galixy- Real (not a fact but come on all the events leading up to human egsistance odds are it happened somewhere else. mabie not anyhtign like a human mabie the same thing but years more or less advanced. )
The face that in our lifetime we will never know- Real (fact everytihng is so far away we will never know for a fact about other intellegent life)

This is just the way i see it.
