Extraterrestrials impact
The impact and explanations to the existence of a lot of external bodies we have experience on earth grows more intense by the day. This is occasioned by the appearance of most of the unidentified flying objects. But here, the problem is not only with the UFOs as they are rightly called. There has been some discovery of bodies and some thin layer of melt glass seen as a result of some cosmic volcanic eruptions from other planets.
There has been a confirmed existence of some contemporaneous levels of melted glass eruptions dating more than 12, 900 years ago. However, these were mostly discovered in two continents and are believed to have resulted in some siliceous scoria-like objects (SLO's). There is also a sort of tick charcoal melted layer that is discovered in Syria spanning up to12, 900 years old, which is believed to have melted under a temperature as high as that which can boil and melt sand.
This has been associated with such issues as the Younger Dryas Boundary hypothesis which explains the occurrence of some cosmic impact 12,900 years ago to spark off a Cold Climatic era.
While the aforementioned has been discovered long ago, a new set of scientists including known names like James Kennett have in recent years discovered a very thin layer of sedimentary rock that dates back to 13,000 years. This was discovered in Pennsylvania, South Carolina and then Syria. They all has the same properties and is believed to have been formed at a temperature of up to 1,700 to 2,200 degrees Celsius which results from some cosmic bodies having some impact on the earth.
There is no evidence that the melt glass is man-made or even volcanic, but the truth is that it has and shares some characteristics with the charcoal layers of Syria, and the eruptions of the Younger Dryas Boundary Hypothesis.
