I recently and quickly voted to close this question but after considering comments by @shigeta I voted to reopen. When I first read the question, I thought it was rather silly. Yet, I realized I would never shut down a question from one of my students so quickly. I would instead try to answer the question. So I think I acted rashly without considering the potential value of the question, not only to the person asking but also for future readers. The same idea applies the question about surviving on non-life. The questions may seem superficial or silly but perhaps there is deeper biological understanding that could be conveyed in the answers.
As I am new to this community and have recently achieved some moderation capabilities, I would like to learn what you all consider when you decide whether to close a question. Until I have a better feel for moderation in Biology.SE, I think I should hold back until I learn more. Thanks.
