Over time, we have seen repeated examples of people or ideas who have been labeled as crazy.

People scoffed at the thought of the earth not being the center of the universe.

People disbelieved the existence of unseen organisms called germs,

couldn't conceive of the possibility of space travel,

and laughed at the idea that people would desire

computers in their pockets one day. William Harvey, the first scientist to accurately describe

blood circulation, published his theory in 1628, claiming that blood passed through the heart,

not the liver, which was the 1500-year standing school of thought. He was criticized so

strongly, his medical practice suffered, and he became a recluse, saying, much better is it oftentimes

to grow wise at home and in private than by publishing what you have amassed with infinite labor

to stir up tempests that may rob you of your peace and quiet

for the rest of your days. Nowadays, we've made some big strides in opening our minds to various

possibilities, and the scientific community in particular is hesitant to label something as truly

impossible. The notion that we are alone in the universe seems to be one of those

dated ideas, especially given the fact that numerous government officials have testified under oath

regarding the existence of non-human biologicals. But still, abduction cases seem to be our new line in

the sand. They are just a little too far-fetched for most to believe

we can be plucked from earth, studied, and placed back into our beds, or our cars, or our canoes.

It almost goes without saying that not every account of sightings or alleged abductions can be

taken seriously, but you can't help but wonder if some of those people

are modern-day William Harvey's just waiting for the rest of us to catch up.
