Roy Plotnick has a new post over on Medium.  In this one, he ponders the possibility of alien life and whether it could have visited Earth…

I had not been able to get out into the field for months, so on the first warm day of spring, I headed to a nearby outcrop of Ordovician rocks, one I had visited several times before and always yielded some interesting fossils. For hours I contentedly hammered away, stopping every once in a while to examine the surface of a slab to see what it contained. Trilobites were especially exciting. Bang! Bang! Clink! Clink? A glint of metal caught my eye. Initially, I thought it was one of the many pieces of trash dumped along the roadside. With a jolt, I realized it was deeply embedded in the rock. Meteorite!! Meteorites had been found in other Ordovician age rocks, so this was highly unusual, but not unique. Then I took a closer look. This was no meteor; it was a refined metal and was flat, not round. Spaceship!! I had found the first evidence of an alien visit to Earth! Fame, fortune, an appearance on the Late Show! Then I wake up.
