What does an encounter of the first kind involve?

The seeing of a UFO or alien spaceship is what is involved in an encounter of the first kind. This is the first in the four categorizations of UFO incidents. The succeeding encounters are as follows:

1. Encounter of the second kind: evidence, such as the marks that a UFO or an alien spaceship may leave on the ground.

2. Encounter of the third kind: meeting with a space alien.

3. Encounter of the fourth kind: actual abduction by aliens or removal from the scene at which you witness the UFO.
