Being rational all the time is keeping your nose in the poo and reporting on the stink.
I think this is an extremely irrational way to look at the universe and human condition.
We humans have evolved in such a way that with our hands and minds we are the most powerful creatures on the planet. Because we are so accustomed to having power, any and every situation where we are not in control - where we are powerless - becomes amplified in our minds. We are problem solvers, and we hate problems we can't solve.
Even the rational sometimes forget just how much we have conqured in so little time. So many things we used to be powerless against but no longer are. Preditors with large teeth were a threat 4000 years ago, but probably not something you worry about now. Whereas a century ago earthquakes would devistate cities and kill millions - with modern engineering we may not be able to prevent quakes, but we are much better at enduring them. We have established working strategies that if properly employed can save millions of lives.
If an alien visitor were to come to earth, and take a human up into it's spacecraft... but then all it studied was what waste we excreted and what we couldn't do - we would likely take offense to that. Judging purely on faults is irrational. Being rational means understanding both our weaknesses AND our strengths, and reporting on BOTH.
Now back to the original thought - I think religion isn't just a means to escape reality (the reality that there are some things we are simply powerless against), but also to escape responsibility. We have a remarkable capablity to solve our problems - but that takes cooperation and hard work. On the other hand, if "only god" can solve some problems - then we don't need to bother trying to solve our problems ourselves, do we? Why spend 20 years studing communication, math, physics, chemistry, biochemistry, microbiology, and what others have done in cancer research - when one could simply dismiss such effort with 'only god can stop disease forever'. Why bother learn about other customs, other world views, and learn how we can all get along - when it's so much easier to just conclude "god will destroy those that don't share my world view."
