Answer:
The UFOs
Explanation:
This person is saying that it either had to be hallucinogens or the UFOs which is false, because it could of been a number of things, ie. Comets, planes, helicopters, rockets taking off.
This is the kind of concept a utilitarian would agree on. If the result is positive for a large group of people, we should seriously consider doing it.
However, I would like to comment on this concept. In my opinion (and that's what you're asking for) there are situations in which the ends don't justify the means. You can e.g. think about mass-bombings to fight against terrorism. However, the possibility exists that innocent people will be hit, and will die. Therefore, the end don't always justify the means (in my opinion).
