In an excerpt from Imagined Life: A Speculative Scientific Journey among the Exoplanets in Search of Intelligent Aliens, Ice Creatures, and Supergravity Animals, we learn,
In addition, we don’t have to assume the standard science fiction galaxy populated by bipedal hominids that speak English to understand how natural selection might operate on other Goldilocks worlds. We can look at the development of intelligence and technology on Earth and draw possible analogies to similar Goldilocks planets in the galaxy.
The key point about natural selection that we have to pay attention to is this: it is not a process that selects for niceness or moral worth…
So what does this tell us about the types of life forms that will develop on Goldilocks worlds? We’re afraid that the answer isn’t very encouraging, for the most likely outcome is that they will probably be no more gentle and kind than Homo sapiens. Looking at the history of our species and the disappearance of over 20 species of hominids that have been discovered in the fossil record, we cannot entertain a hopeful attitude toward the possibility that we will encounter an advanced technological species that is more peaceful than we are. Anyone we find out there will most likely be no more moral or less warlike than we are. Scary!

Fascinating to be so sure when we have no evidence of any space aliens at all. A religion underlies this, you may be sure.
By the way, there is no evidence that our branch of the human family killed off the others. Lineages can die out without anyone killing anyone else off. For example, small groups are often simply absorbed into larger groups.
