Question 1: Assume we find definitive evidence for microbial life on Mars or Europa and would the discovery alter your view of our place in the universe? If so, how? What if we made contact with an intelligent species from another world? Do you think it is likely that either kind of life exists elsewhere in the universe? Do you think that either kind will be discovered in your lifetime? Explain.

Question 2: If you had the chance to communicate with an extraterrestrial, what would you like to ask him (or her, or it)? What do you think the answer might be?

Question 3: If we do contact another civilization, how much should we tell them about us? Is it a risk to discuss our weaknesses? Do you think they are likely to try to attack? If so, why? Science fiction stories have suggested many possibilities, from using us as food, to enslavement, or possible alliances against their enemies. Pick one or more possibility (not necessarily one of these), and discuss it.

Question 4: In Star Trek, Dr. McCoy often told Captain Kirk that something was "Life, but not as we know it."

Describe some kind of life that is not life as we know it. Explain how it gets energy, what it does, where it lives and how it reproduces. You may use an example from a book or movie, but an original idea would be better.
