Bob Lazar said the advanced spacecraft he examined used a fuel source called element 115. He said it did not occur naturally on earth. (hivelink)
What if Earth has a large deposit of element 115 somewhere? Perhaps when Theia hit earth 4.5 billion years ago, it deposited element 115 in two great blobs in the earths mantle.
(hivelink)- Perhaps at least 100 million years ago, another technological civilization evolved on earth and found 1 decent deposit of pure element 115 very early in their history. tid:3429 (1) (hivelink)
