Human etchings half a million years old?

The uncertainty of science: Did an ancestor of humanity etch zig-zags on a shell half a million years ago?

This story is a fascinating illustration of the difficulties of pinning down facts in the field of science. The researchers do an impeccable job of checking all possibilities, and finish by cheerfully admitting that their conclusions could be wrong. If right, however, the discovery is significant, as it tells us that 500,000 years ago an ancestor of the human race was capable of drawing an abstract design on the surface of a shell.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

    Two more examples of how the history of man has to be further studied to be properly understood:

    Globeki Tepi

    And the Indian city of Dwarka

    http://youtu.be/nQZFS9Hij0M

    Both established to be built aprox. 11.5 to 12 thousand years old. Globeki Tepi is an elaborate stone construction related to worship possibly representing the symbolic disconnecting / transition from hunter gatherer groups to agriculturally based societies / civilizations. Much older than the pyramids which in themselves are fantastic achievements with the technology of the day (how old are the pyramids really?). Built and then over time totally buried by hand, and the City of Dwarka on the coast of India now under 200 feet of water. So old that when the real deal melting of the ice sheets was in the process of increasing sea level by 300 feet. Possibly the real basis for Atlantis.

    Human beings, potential unlimited.

    Just goes to show the invitation to “come up and see my etchings” is an older line than anyone thought!
