It may very well be ridiculous to you, but, from a perspective of Psychology, species we know on earth that are predators are by far the smartest in
the animal kingdom.
Extending that out into speculative xenobiology, we should expect a higher likelihood of meeting aliens whom have evolved from a predator.
How such may have shaped any resulting civilization is additional speculation, but, evolution from a predator ancestor is something worthy of
consideration and caution as it applies to any scenario involving contact with a new species.
Further, an even higher likelihood for encountering Alien Intelligence lies in making contact with Artificial Intelligence Machines, either resulted
from self directed evolution with origins in biology, as creations of a parent biological species, and/or as creations that have long outlived their
progenitors and have self evolved into an entirely new civilization.
Machines should also give us pause in consideration that we don't really have a true model for AI machine interaction.
Suffice to say, however, most scenarios modelled on what we can speculate on regarding contact with AI Machines have a higher probability of playing
out in ways that result in our extinction.
All this love and light and hug a brother alien stuff is an illusion perpetuated by the New Age cult mentality that's attached itself to the UFO
phenomenon in building a marshmallow soft friendly alien mythology, that, in itself could be considered rather conspicuously suspicious if taken in
terms of 'fattening up' and 'domesticating' the cattle.
All in all, as nice as it would be to make contact with Vulcans, or Some TV Personality Photogenic Friendly Aliens, the likelihood, if contact is ever
made, is higher probability for either a non-threat event as in discovering the remains of a dead civilization somewhere, or bumping into space
travellers that will be just as opportunistic, hostile, and deceptive as we are, if not more so.
One doesn't leave their planet or point of origin if the point of origin is perfect. Leaving 'home' typically involves a reason beyond just
exploration and satisfaction of ambiguous curiosity.
