In all 3 synoptic gospels, Jesus prophesized at his trial, that people there will see him return from the clouds. These people will be over 2000 years old! Where are they? The whole earth has been mapped at 15 cm (6 in) resolution, so there are no hidden villages in some remote valley. Their age can be confirmed by isotopic analysis of a bit of tooth enamel using a sensitive mass spectrometer. So unless x-ians can show a lot of 2000-year-old people, we can either dismiss jesus as a false prophet or dismiss the new testament as true.
