Of course aliens are real. They impregnated my wife while I was away on a business trip.Unidentified flying “objects” have been observed by many reliable observers, so they existed. What they were is another question.
Personally I don’t think ET crashed at Roswell in 1947. Evidence can easily be faked, but human nature stays the same. And the US government didn’t behave as though such an event had occurred.
