1) Does the fact that the entire galaxy was involved in bringing forth life on Earth change your perspective of Earth or life in any way? Explain. (Take the stance that my belief in extra terrestrial life in the universe is increased.)

3) How did the Big Bang go from being an idea to a theory? Explain.
4) How are the cycles of matter on Earth and in the galaxy similar?
