in my opinion

To find the evidence first you have to understand the phenomenon. Including the phenomenon of finding evidence is easier.

The most important evidences are on the body of the adduct, other evidence is difficult to find, because they start from the assumption that aliens
make a mistake.

It should be remembered that any Ufo sighting is a mistake, because the aliens do not want to be seen.
