Okay great - thanks for the straight answers everyone. I watched a Nova special about all the things that could easily destroy the Earth - Here's an interesting article about Gamma Ray Bursts. Those are real.
All the nonsense about the triangles though, that's a little too far out and has more to do with pattern recognition.
OK ... let's take this step by step ... here's the picture. First off, I am well aware of Pareidolia and what people "see" - this is not that approach.
The "triangle" aspect (as well as the rounded body aspect) is a representation of a picture of the Orion Nebula which cannot be seen from earth unaided. This image pops up as far back as around 9000 BC, and my avatar is the base representation with the triangle, also known much later in history as the goddess Tanit. That image was also in Egypt, and as time went on the triangle was closed and the ankh as we know it (also the sign of "life") became the norm. The final version was the christian cross where the rounded "head" was close and made a straight line.
Everything about the picture in total has to do with an understanding of how people "thought" and communicated 40,000 years ago, and "woman" was directly connected as a "visual" representation of the idea of "life". So if a picture is worth 1000 words, the goddess carvings were the original "sign of life" in a context of destruction, which "sign" was upgraded the last time ET was here (the 13,000 BC event) and everything should have filtered down to us today, but, it didn't. 3300 BC was the beginning of changes based on a fear of death due to the arrival of Dr L's
MINOR superwave event. The original data was scrapped and everything was, over time, rewritten. We are here today talking about this because of that data change because we no longer know what's going on. ET is here, we have no clue.
The best representation of the nebula symbol was preserved in Newgrange, in Ireland - dating 3400 - 3000 BC and would be a representation of the nebula symbol used during the minor superwave event. While pre-Egypt and pre-Sumer were flipping out, these people kept their cool. If you look at the top pic, you can see both the outward gas flow triangle, as well as the gas outflow "rounded" effect.
