Last Alien Encounter is a fascinating story about a group of ancient nomadic people who encountered giant aliens from another exoplanet 10,000 years ago. The robotic cybermen who were sent to Earth were looking for a rare blue crystal in a remote area in North America, now called Absaroka Mountain in Montana. While mining for several years, they existed on a spacecraft in the stratosphere. Every evening after sunset they left the confines of their spacecraft to work in a cavern. The ancient people who lived close by revered them, and called them Gods from the sky. One day they disappeared, leaving behind a rare blue crystal as a gesture of goodwill in hopes that one day it might encourage intelligent humans to benefit from its powers. The story unfolds as a small nomadic family migrates across the land bridge between eastern Siberia and Western Alaska. These ancient people are looking for resources to survive when they find people who live in a cave close to where the giant aliens work. They watch in amazement every evening as the aliens toil in their cavern. A young girl who traveled with her family admires them and eventually becomes the new leader of the village and builds a great civilization from the powers of the blue mineral left behind. This book is filled with intrigue, greed, and ultra-high-net-worth individuals worldwide. It also reveals fascinating alien technology of nanoscience and intricate autonomous systems and devices that are a mystery to humans. From flexible graphene sponge spacecraft powered by photon energy that can thrust spacecraft through wormholes at great speed to their logical societies' science and technology, which has survived for ten thousand years. They constructed a great civilization that integrates compassion and tolerance into their intelligent autonomous machines – their ultimate goal is to share this ideology and their technology with people on Earth – or annihilate them.
