Intelligent life is extraterrestrial life capable of communication with humans.
And communication doesn't necessarily mean talking. E.g. Dogs can communicate with us - we don't speak the language, but it can tell us that it's happy/wants food, and it can tell when you're not happy with it.
A human being is what intelligent life is.
While intelligence is subjective and difficult to measure, this is a fairly good definition of the major distinctions between humans and non human animals.An un-intelligent lifeform is something that operates because of reasoning and logic.
An intelligent being is something that can operate with reasoning and logic.
A being of higher intelligence is something that can understand reasoning and logic.
Diseases are un-intelligent lifeforms. Dogs are intelligent beings. Humans are beings of higher intelligence.
While intelligence is subjective and difficult to measure, this is a fairly good definition of the major distinctions between humans and non human animals.
define intelligence
(MY Definition)Intelligence is a game which can only be played with hurtful words!
I'll do one better and define intelligence as the capacity to change behavioural survival strategy to meet the current environmental conditions without undergoing a genetic revision. That is: the capacity of an organism or group of organisms to further its own existence in accordance with changing events; above and beyond the slow process of natural and other forms of evolutionary selection.
