    I love how when it is required he is all quirky and funny and when it is time to get serious he is all dark and mysterious. Been noticing this a lot lately, thats very hard to pull off Matt. We small creators are learning a lot from you. Keep up the great work and keep inspiring us small creators like this. Love and peace ๐Ÿ’›

    ~ when it's probably
    strange & funny :
    roll the hands and
    twist some mustache..
    ~ anything can be
    cool or dark stuff -
    so, lay on it with your
    shadow & glee.!
    ~ after noticing
    a secret clue..
    act natural until the
    crowd disperses.!
    ~ when we see faces
    on mundane objects,
    is it paradoeia, or not.!!
    ~ what's hiding
    may be obvious -
    even if not in
    plain sight..
    ~ if ancient things
    died recently..
    you have activated
    a "mortality curse"..!!
    ~ what empty spaces
    are here, for -
    likely slipped out of
    that hole in your
    ~ in the end, you
    might wind down..
    or just pass out
    on the couch..!

    cheers for our
    tireless narrator.!!

    No, no no no no no.
    Neanderthals weren't early humans, but a close relative to us. Two different species, two different natures, two different fates.
    This would be possibly the only evidence of Neanderthal construction, but not of the earliest human construction. That honour goes to what's believed to be an ancient temple in turkey(I've forgotten the specific location, edit pending), which was constructed about 12,000 years ago and marks the beginning of the Holocene era.

    It shouldn't be at all surprising that Neanderthals sought refuge underground. The progenitors of modern man set out to destroy any and all humanoids and made life impossible for Neanderthals! As I've said many a time, the appearance of humans was the worst catastrophe to occur upon our planet! The second worst was the invention of religion!
