    The OP asked if humans are apes in post 121.

    Presumably, Saint has gotten a satisfactory answer, and is now asking this as a followup question.

    Any specific reason that the universe must be so huge?
    Billions of galaxies ans trillions of stars.
    And we only live in a dust - earth.

    From post#1

    You gotta come to the meetings. The OP has moved on to new questions.

    This is not a full sentence. What about communication and accumulation of knowledge?

    I would consider those would be via vocalization as a survival advantage

    It was you who opened the door to vocalization as an attempt to differentiate humans from the other apes.
    Hardly. It's only been around for 50,000 years or so.
    The blink of an eye in evolutionary terms.
    Dinosaurs, having ruled the Earth for 140 million years, would laugh and laugh...

    I am perfectly fine with accepting that the OP has moved on.
    What I am not so fine with is this meta-discussion about the discussion, since it helps no one.
    Disengaging from meta.

    Good. Then we all agree to move on.

    The universe has had 13.8 billion years of variable expansion rate to be as big as it is, simple as that...Space is what separates everything...Time is what keeps everything from happening together. Better known as spacetime, which can be defined as a unified multi-dimensional framework within which it is possible to locate events.. The concept of spacetime follows from the observation that the speed of light is constant and does not vary with the motion of the emitter or the observer. Spacetime allows a description of reality that is common for all observers in the universe, regardless of their relative motion.
    "The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality".

    I don't believe there are Aliens, No UFO,
    only God rules.

    It's OK to believe whatever you want, but if you state it here on a discussion forum, you're expected to defend it.

    In the survival sense, the same may be said about intelligence. Look at bacteria for example, different forms seem to exist everywhere.

    Yes. That was my point.

    The proposal was to confer some human right on some of the great apes. Not to think of them as human but to recognise that they deserve to be treated like they were.
