The most significant open questions in astrobiology are How did we get here?  Where did we come from? Are We Alone in the Universe? These are most significant because they are the main thing that astrobiologist study daily. The main question is Are We Alone? But in order to answer than you need to ask and answer the other questions as well. If we know where and how life started on Earth then we can figure out where and how it can start elsewhere, the perfect habitable conditions for life.  A lot of assumptions must be made when looking for life because we only have one main data point to work with. We assume that life elsewhere will progress at the similar rates as ours and eventually a someone similar intelligent life will be present if life isn't wiped out all together.

The SETI Institute is a not-for-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations. It aims for discovery and for sharing knowledge as scientific ambassadors to the public, the press, and the government.  SETI stands for the "search for extraterrestrial intelligence".  (SETI) This institution takes the assumption that life will evolve similar to Earth and is actively looking for intelligent life with the capability for communication similar to humans.

Big question in Astrobiology is where did we come from? What is the origin of life on Earth. This is still mostly unknown, there are many ideas and hypothesis as to what happened to kickstart life but there are very few facts and answers. It is agreed upon that all life came from one LUCA or last universal common ancestor (Schopf 2002). If we could answer how life started on the only data point we have then it would set us up to unlocking how life starts on other planets or even engineering life on Earth.
