Occasionally Carl Sagan, the astronomist and space scientist at Cornell University, writes an article for common consumption in popular journals or Sunday magazines. He titled one article, "Is There Intelligent Life On Earth?" In this essay Sagan explains what an alien spaceship might reveal about our planet and ourselves. Visitors in an alien spaceship would have plenty of evidence and clues to surmise a great deal about our planet. They would be able to characterize our environment, detect definite signs of life and find manifestations of intelligent beings. The summation of all that would encourage further exploration of the planet. However, further study of what is taking place on this planet would produce puzzles for the alien observers. They could detect that there is much that is going wrong on this remarkable planet. The living beings who are working the planet have reworked its surface in extremely harmful and dangerous ways. They are destroying the ozone layer, devastating their forests, eroding the topsoil. In addition, they are performing massive uncontrolled experiments on the planet's climate. It would appear that these beings are absolutely oblivious to their fate. Can they find no way to work together to preserve the planet that sustains them? Aliens would have good reason to ask if there is intelligent life on earth. The prophet from Tekoa raised the same kind of question a long time ago for a different but related reason.
