Cosmology, Astrobiology: The Biological Big Bang. Panspermia & Origins of Life

Thirty three chapters written by the top scientists in the world, explaining the origins and evolution of life, which arrived here from planets much older than our own. As detailed in this landmark book, life has a genetic ancestry extending backwards in time over 10 billion years. The genetic seeds of life flow throughout the cosmos. Life on Earth came from other planets, and was deposited on Earth, repeatedly, over 4 billion years ago as there is evidence of life in this planet's oldest rocks. Life was delivered by comets, asteroids, meteors, and planetary debris which crashed into the new Earth. Bacteria, archae, and viruses can survive a journey through space and the ejection from and crashing landing onto the surface of a planet. Meteors older than our solar system, contain microfossils of bacteria, archae, and viruses. Viruses serve as interplanetary genetic libraries, and accompany microbes which act as genetic messengers from the stars. Once they crashed upon Earth, these microbes and viruses exchanged genes, creating multi-cellular eukaryotes which began to evolve. Life is everywhere in the cosmos, and there are clues that life may exist on Mars, Europa, and possibly on exo-solar super-Earths and water worlds. Earth is not the biological center of the universe. Our ancient ancestors, journeyed here, from the stars.
