Many ask me why I'm Atheist. I'll tell you why, it's only common sense. But if that's an invalid reason here's an essay.
People have to be on crack to believe that bullstuff about life after death and some magical being that created the omniverse and somehow spawned everything WITHOUT using up energy or matter thusly breaking a law of physics (along with the other 2334896793468 it defies). I mean... seriously, think about it.
God is sitting there in complete NOTHINGNESS no empty space or ANYTHING. So, he is now sitting in a place with zero room. There's no universe yet, he can't exist until AT THE VERY LEAST the universe is created so that space and time exists. Let's pretend he COULD have created the universe (which is also impossible because he is made of atoms, like every other bit of matter and atoms haven't formed yet). The massive amount of heat and energy and matter would instantly kill him. Besides, if mere PARTICLES don't exist yet, neither can the clouds making the heavens.
MUCH LATER
He finds a ball of rock and magically points his finger and somehow BLAM instantly a river and mountains and grass forms instantaneously (okay, maybe it took 7 days,but you get my point). Explain to me how this is physically possible. ALSO, how can angels, when they are created from DEAD (if you're dead you are not alive, you have no working brain and are dead you cannot live plain and simple, again angels are impossible) and somehow grow wings, how the hell would they fly up and in no time at all they switch dimensions into this magical realm of pure clouds. Which makes your brain (which is actually DEAD right now) automatically get happy.
TL;DR:
RELIGION MAKES NO SENSE. YOU HAVE TO BE ON DRUGS TO BELIVE IT AND EVERY LAW OF SCIENCE AND LOGIC DEFIES IT.
