We Are Alone… Probably.

If one considers the events which led to the evolution of life on this planet (and I’m assuming we’re not at our pinnacle yet, nor the only dominant species that the Earth will throw out). The odds of the same or approximate circumstances occurring in another part of space are improbable, but still very very possible.

However, given the expanse of space and time we hit upon a physical and temporal logistical issue. The nearest star to our Sol is Proxima Centauri C, a mere 4.2 light years away, and still beyond our reach. The furthest galaxies that we have currently observed (through Hubble or gravitational lenses — quite literally using the gravitational effect of in-between galaxies) are approximately 14.5 billion light years away. Plenty of space and environment for independent life to evolve, so unlikely that we will ever make contact due to the distance and our inability to focus on projects that go beyond a term of government.

Temporally, the universe is old. Current theory suggests approximately 14 billion years, life has existed on Earth for ~3.7 billion years, the universe may well continue in existence way into a googleplex of years. So, we hit our next barrier to first contact; both species actually hitting their technological peek at the same point. Assuming all space and time faring requires technology, and is not a feasible natural trait.

Taking this in to account, we probably have a better chance of meeting inter-dimensional species, as opposed to extra-terrestrial species. Or extra-terrestrial species that are also inter-dimensional, where logistical definitions made here quietly pop down to the pub for a sly one on a Sunday afternoon, just as our new friends sneak our of their dimension for a joy-ride with the neighbouring provincial dimensions.

Food for thought?
