Aliens and Creationists

I am beginning to believe that the ability of ordinary people to think is vanishingly small and probably smaller if you are a creationist or IDer. And, no I am not talking about the candidacy of Donald Trump. I am talking about the creationists’ obsession with aliens. Apparently their god didn’t create any. How they could know this is quite beyond me.

One aspect of their blather is the so-called Fermi Paradox which is neither Fermi’s nor a paradox. The FP goes like this: if aliens exist, some must be very advanced and have noticed us by now; where are they? It sounds reasonable, but the obvious answer (They don’t exist!) is unwarranted.

Just put on your thinking cap for second. We have been producing radio waves and other electromagnetic signals for a bit over 100 years. So, lets be very conservative and say that there is a bubble 500 light-years in radius that our presence can be detected. (500 years of travel at the speed of light in a vacuum is a reasonable maximum supposition). The universe as a whole is 14+ billion light years in radius, so what percent of the entire universe does our “close enough to notice the humans” bubble consist? Since the volume of such spaces is proportional to a cube of the radius, the percent is (5003/14,000,000,0003) x 100. I will do the math for you .. uh … essentially zero (It is 0.00000000000000000000000455%.) This is also the probability that any aliens would fly through our bubble and notice our presence. This assumes that the aliens had sufficient technology to fly around faster than the speed of light and other apparently impossible abilities.

Now, those are the spatial odds. Regarding time, our 500 years is a very small fraction of the time the universe has existed (14+ billion years). Let me be generous and assume that the first 4+ billion years were needed for alien life to evolve (the creationists creator need not be so limited) so with regard to time, we have been signally for (500/10,000,000,000) x 100 = 0.000005% of the time period since life began in this universe (approximately). So, the aliens would have to be alive and looking during our time period to find us, no? So, the probability that aliens would find us is the product of these two probabilities, the spatial and the temporal probabilities, which is 0.000005% of basically zero.

So, for all you creationists who are asking “Where are these aliens?” Shut the fuck up and sit down. Besides, we really do not want them to find us. History shows us that when more “advanced” technological societies meet less advanced, it doesn’t go well for the less advanced.
