"When Jesus described the events that will surround His second coming, He said, “Just as it was in the days of Noah, so will it be in the days of the Son of Man. They were eating and drinking and marrying and being given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all” (Luke 17:26–27). Jesus was pointing out that, although the people of Noah’s day were totally depraved, they were not the least bit concerned about it. They were carrying on the events of their lives without a single thought of the judgment of God."

"Steven Quayle spoke of an occurrence, still classified by the US Government, in his popular Radio Show “Coast to Coast”: the events allegedly happened in 2002 on a desert part of the Afghanistan, when a U.S. Army squad went missing. A Special Ops Task Force was sent to find out what had happened, and the soldiers walked along a ragged, mountainous trail until arriving at the entrance of a large cave. Pieces of broken U.S. military equipment and gear were scattered all around the clearing. The Task Force was about to enter the cave to explore its recesses when a 13-feet, red-headed, six-digit, double-toothed humanoid emerged and attacked them.
According to the witnesses, the giant pierced one of the soldiers with his long spear killing him, before the rest of the squad could take him down, shooting at his face for thirty seconds straight.
The body of the giant was packed and loaded into a helicopter, and transferred to a secret location in the USA for study.
Based on Quayle’s story L.A. Marzulli succeeded in identifying and interviewing one of the members of the Task Force who actually saw – and shot – the Giant of Kandahar, as the event became to be known."

"XIX. The Three Mysterious Tunnels
The discovered tunnels are thousands of miles in length and lead to three different areas of the planet. The one in the left connected the Romanian base to a yet to be discovered underground base somewhere in Egypt (which was definitely discovered and explored by now).
The right tunnel led to a similar but smaller structure, in the “Tibetan Plateau”. This tunnel had three secondary ramifications. One led to an underground area near the Romanian city of Buzaru (close to the “Carpathian Bend”). Another one led to the already mentioned Iraqi base, while the final ramification led to an underground base in the
Intense preparations begun for expeditions inside all 3 tunnels, as following: the first one to Egypt, the second to Tibet, and the third one to Earth’s core."
