The Odds of Life Elsewhere

For over 50 years, scientists have been scouring the solar system for evidence of life outside of planet Earth. The first ever probe, the Venera 4, was sent to the planet Venus by the Soviet Union in 1967. It is from this mission that we gained our knowledge of the planet’s atmosphere and the scorching temperatures that make it categorically uninhabitable for any known species. Of course, in a galaxy of infinite possibilities and undiscovered terrains, the odds of the human race being the only species in existence are slim, but that doesn’t mean we are any closer to making contact with other intelligent life-forms, and certainly not any with whom we would share many characteristics; at least, not in our solar system. So why do so many Earthlings believe we have been visited by extra-terrestrial beings, and are they right?

We may never know the answer, but we can consider it, hypothetically. Imagine the solar system as a big roulette table. The chances of finding a habitable planet can be compared to the chances of landing on red, or black, or whatever you need in that moment to win. Earth is, currently, the least hostile planet by any standard. The temperatures on Mercury, Venus, Pluto and Mars alone are each on one extreme end of the spectrum at all times, and the landscape and sensory stimulus are decidedly lacking. Should there be an alien population sharing our galaxy, and should they also have the science of spaceflight at their disposal, you can bet that Earth would be top on their list of planets to visit.

With the fear of human extinction and the destruction of Earth growing, more, efforts are being made to find a viable option to re-habitat the human race. This thought, in relation to how little we still know about what exists beyond us, makes it easier to empathize with theories of crop circles and alien abductions – or, at the very least, with the ideas of life elsewhere and inter-terrestrial communication.
