You closed your eyes and bought into modern perceptions of these ancient reports that are quite more realistic and down-to-earth than what modern interpretation made out of them.
>angelsThis concept comes from the Greek Angellos and means messenger, such as the Arab/Hebrew Malak(im). These messengers are sent by their respective lords and are made of flesh and blood. They travel from their respective home worlds to this planet by the means of flying craft, a fact that has been reported all over human history. See Hesekiel and Enoch in the Tanakh, as well as Buraq in Arabic lore. Without these means, these messengers can't travel, nor can anyone else.
>ghostsThis concept is rather split, with one part being parapsychologic in origin and resulting from peoples problems being "imprinted" on the surrounding environment, the other being entities ("dudes") playing games with humans. German researchers did studies into "ghost" phenomena and mostly explained them conclusively as being psychological expressions that actually have physical effects on the environment. There are however also prominent ghost apparitions that are actual people who got "stuck" or treated in a certain way to exist in that form. I don't know how, but I'm pretty sure science can explain this in the future, if people did research into that.
>aliensThis concept is a result of arrogance and ignorance, since everything not originating from earth is "extra-terrestrial" and thus "alien". It's no secret other planets and galaxies have existed before earth did, so we are not the center of the universe. The fact that "modern science" continues to perpetuate the geocentric world view of the Roman Catholic Church in this way is an insult.
