How did the universe get here? If it made itself, then it completely contradicts the "logic" of cause and effect. You don’t get, "the effect made by the cause", because it doesn’t make "sense". The universe has not always been here, because if it did, than right now all the energy that went into making it would practically be depleted, since as "science says", it is expanding at an exponential rate, and therefore it becomes colder and colder every year. This is because it has to use whatever energy it has left to fill in the space. Matter is made up of quarks, which is energy. Did you know that? Energy is ironically immaterial as well, interesting how that plays out...
Anselm's definition of god, is that "it is the greatest possible thing that can be conceived of, and since something real is greater than something that is not real, than that thing must truly exist. This definition only works for god, as most definitions only work in seperating one thing from other things. If you honestly stop to think about it, a god must actually exist.
One interesting concept of the soul was suggested by Socrates, who much like Descarte, emphasized his "innate ideas" which are ideas that are already in our head, without ever having been conceived of in the real world. We have little know how on where they come from, but that doesn’t prove that they are not there. These are things such as having the concept of something that isn't perfect. We all know what a perfect circle would look like right? However it is physically impossible to draw one, or even a perfectly straight line for that matter. The very fact that nothing is absolutely perfect, shows that we got this idea through our own mind; completely distinct from any material sense at all. And yet isn't perfection considered a real thing, "to strive for?" (some suggest that human cant exist in a real world, which is why it isn't perfect: "the matrix" for one) It is actually your dear friend science that introduced quantum mechanics, which is also beginning to disprove allot of the dictations of a completely material reality as well. Matter is actually made up of energy, and that is considered an immaterial thing
So the logical fallacy in your reasoning, which is appealing to authority, is very ignorant, and your giving science a bad name by saying that it proves the nonexistence of god. Who is to say that god doesn’t exist, and who is to throw truths in places where we just can not know, due to the fact that we as a human race are to stupid to get beyond our own circular arguments? I believe in perseverance, and the existence of god.
Im a Rationalist, or at least I consider myself one. As for being Catholic, yes I am, but I am also, a philosopher, and enjoy looking at my beliefs instead of blindly accepting them without having a warranted cause. Warranted in respect to having evidence for justification of a statement. "I believe" does not imply that "I know", "I know" implys that "I believe". The fallacy in most peoples reasoning is that, they believe in god, because the bible says so, but how does the bible know, when there are fifty other religion’s that say different things about the afterlife, but were each apparently drawn from some "Devine revelation"? The answer is simple; to believe the bible is right because it says so is a logical fallacy (known as begging the question, or circular argument). I derive truth from reason, which gains facts from warranted, true beliefs.
