Ufos
Universe, deep and complex, is surely one of the biggest source of questions in the world. Human wants to understand black holes, planets and wants to know if other civilizations exists.
Ufos are objects coming from out there and they can be naturals or created by an other civilization. But if they are, there is one question: Why don't they communicate with us? Should we try to communicate with other civilizations?
Some questions have to be asked the questions about communication for example. If we think ufos can come to earth, we think other advanced civilizations exists but is it a good idea to communicate with people who own a technology as powerful as one which can be used fort going from one point of the universe to an other quickly?
If they own this type of technology aren't they powerful weapons owners? If this technology exist, maybe it needs a lot of natural or non natural supplies? So the problem is easy to understand, if we can not know if we are stronger than an other civilization, communicate with her can be dangerous for us, it could be the and of our civilization we we find an other stronger than our, or one who wants to fight against us.
In an other way, we can find other people, less advanced than us. If we know what human did on the past in latin america or other parts of the world where settlers became colonialists, we can be afraid about ourselves.
In many cases, trying to communicate with ufos seems to be a bad idea, human is too young to do such an hard enterprise as this one. We have to understand we have time and we can keeping watching space and ufos and try to visit planets like Mars but maybe we could be too weak in front of an other civilization.
