Earth
Our home
The Earth is our home. It has been around for 175 billion years + !!! It has long been theorized that the dinosaurs were killed off by a large meteorite striking the earth, this week, a part of that meteorite was discovered. Aparently, there is a thick black band in the rock between what is the age of the dinosaurs and the current ages. A scientific group believing that the impact site was the Gulf of Mexico did some deep sea drilling into that black band and found a small piece of Irridium. Irridium is rare on earth and is usually brought to earth by meteorites. Testing on the sample is still being conducted.
