An enlightening adventure in the history of life GENESIS An enlightening adventure in the history of life 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. How was the Earth created? What is meant by “gravity”, “dust” and “mighty engines of the sun”? Were there human beings at the beginning? What does “life evolved” mean? Can we find “echoes of chaos” nowadays? “Glacier, wind and water”: what was their role in the formation of our planet? After what events did “our world we know” come into being? What does “sea floor spreading” show a continuous change of? When was the great “rift”? Where did we find the “genesis of man”? Is man “a hostage to the natural powers of destruction”? What process creates mountains? Are the Alps young or old? How old is this mountain range? Where is the Earth’s earthquake zone most visible? What will happen in 15 million years to California and where in California? What happened in San Francisco in 1906? What does “it was levelled” mean? Do we fully understand how to profit Earth’s resources? Have the Alps reached their full height?
