    I see it like being overtaken on the highway — there are very few reasons for aliens to expend the energy needed to physically interact with us in the first place. And the reasons to do such a thing include:

    1. Halt our expansion into the universe because of our penchant for destruction
    2. Claim our planet for their own after destroying theirs
    3. Extract our resources
    4. ???

    After expending the energy and resources to get into Earth’s orbit, it’s probably a lot more efficient to subjugate or destroy the dominant life form than to try and figure out how to communicate with it to achieve the above objectives.

    Back to the highway analogy: most aliens wouldn’t want war with us… but we’re unlikely to ever cross paths with such beings in this vast universe, due to either time or distance.
