Statistically Likely; Scientifically Interesting; Societially Concering

I think that it is highly unlikely that humans are alone in the universe. Data from the Kepler telescope has estimated that there are around 300 million habitable planets in our galaxy alone. It is also estimated that there are around 100 billion galaxies in the known observable universe. It is statistically likely that there is some form of life elsewhere in the universe.

While whether or not we are alone does not directly affect our life on this planet, it matters a lot to the scientific community. If there is life on other planets out there, both our knowledge of life and how evolution works would be advanced. Science is all about learning and determining the truth, so knowing the answer will advance science.

The important question to ask ourselves is how we can prevent ourselves from acting prejudicial and discriminating against life on other planets should life be found elsewhere in the universe. I think that one aspect of this is to ensure that scientists and researchers play a larger role in the research and policies around alien life, (assuming it is discovered); and distancing politicians and religious leaders, (to try and avoid biases that could cause serious harm).
