I am a researcher in African History. I also am an amatuer astonomer, an American Sign Language (ASL) interpreter and a poet.
An important thing to note is that all life will not develop like our own. Just because we are carbon based and need certain temperatures and water doesn't mean all life will. There could be something as insane as life on a planet as far, or farther than, Pluto.
How many planets support life?
