You're kidding, right? What you're saying is that because we don't know something, it's okay to invent whatever fiction or mythology will provide a suitable answer and then say this is "truth." Utter poppycock.
Science came from religion. Science says that even a half truth is better than no truth, which means you come up with a theory of hypothesis, such as the big bang theory, the unified field theory, quantum theory, or the theory of relativity, and then you continue to test these theories until they break and another better theory is invented, but it's still part of the discipline of science to attempt to answer the unanswered, and this is the same drive that came originally from religion. Why became how.
I say you are completely and utterly wrong and that by using the god cop-out, it is the theist that "limits" himself. What reason, then, is there to look for answers if you can say god did it or the tooth fairy took the tooth; or the sandman made you sleepy; or coyote tricked you; etc.?
The athiest never will ask why, and will only ask how, so the athiest is limited by the fact that the athiest isn't even attempting to ask certain questions. Example, if we assume there is a God, then we can discuss how to create a universe, and how to create lifeforms. How would an athiest come to these questions without myths? It's not like we have the technology today to even pretend to ask some of these questions, but the creation myths predicted some of the science we have now, like genetics, and space travel, and solar energy. Newton believed in God, Einstien too, Bohm too.
By not falling into the superstitious nonsense of religious cults like christianity and islam, I'm able to go on observing the universe around me and to be in complete awe at what I see.
You assume every religion is based on superstition. Some religions are based completely on science, such as, STRING THEORY! Such as, BIG BANG THEORY. Many people believe in these two theories and unless you can prove them wrong with science, and if they are ever proven right, you'll have to deal with the new scientific religions that are forming based on the backing of scientific discovery.
I don't need whatever the in-vogue god is of the day to make my life any more complete than it already is. Nor do I need to have some superstition in my life in order to find a reason to live or something to "aim for." And, anyone that does is a truly pathetic excuse for a human.
Exactly, you don't, but then you are disconnected from the universe itself also because if you don't realize that your body is not real, it's just a bunch of atoms, and you are essentially a biological machine, well, okay, who built you and what is your purpose? Even an android on Star Trek would ask this question. Even if you discover you created yourself, don't you want to know who you are? Or are you satisfied being a machine? Be a robot if you want to.
