Our problem is not a predetermined clash of irreconcilable genomes. Racism is generated and empowered by a flawed worldview that can be corrected wit… - Guy P. Harrison

This is not how the 21st century was supposed to be going for us. As a child nurtured on Star Trek reruns, I imagined our species solving poverty, ending war, and colonizing other worlds by now. Silly me. Here I am today discussing a popular belief that reptilian extraterrestrials reside in Buckingham Palace.

In 1972, from a distance of about 18,000 miles away, an Apollo 17 astronaut took a photo of the Earth that later would be named "The Blue Marble." That single unprecedented image of an illuminated Earth in full jolted billions into contemplating the beauty and fragility of our tiny home in the dark expanse.

Isaac Newton would be the easy answer [for greatest scientist ever]. But I'll go with a hominin, probably two million years or so ago, who first confronted fire like a scientist. He or she observed the flames, thought about it, formulated an hypothesis, experimented perhaps, and then came up with a theory of fire. That person, so long ago, was doing science. That person approached fire, a dangerous phenomenon, and dared to control it. That was science in action. And it changed us forever. With fire in our minds and torches in our hands, we were no longer prey, no longer lost in the darkness of every night. If we one day spread our intelligence throughout the universe, it will all trace back to that hominin and that moment.
