Here's a hypothetical story to illustrate a point.
"A recent report came out stating that as many as 1 in 4 people have sunpox. But is the world at risk? A simple bit of math based on some decent assumptions shows that there may be billions of people potentially infected. '... astronomers studied 166 people within 80 miles of New York, and did a survey of the people they found. What they found is that about 1.5% of the people have a terminal virus, 6% have a virus, and about 12% have people think they have a virus. This sample isn’t complete, and they cannot yet detect the sunpox virus as it is still being studied in the one reported case of it globally. But using some statistics, they can estimate from the trend that as many as 25% of the people have the sunpox virus!' Proving this directly has proven to be an issue..."
For those that may need me to connect the dots for you, how likely would you say that the world needs to be in fear, based on the story above, of the sunpox virus? Now read the headline and synopsis again. How likely are you to believe that there are habitable planets out there just because we live on one? I'm not saying there aren't any out there, though I doubt there are any that have developed with intelligence, but with this kind of thinking it makes science look like a young child trying to jam a piece of the puzzle into a hole that it doesn't fit into.
