Everybody who says god exists, is incredibly stupid. I'll first start off with "prayers".
To everybody here who is religious, who has prayed before. This one is for you. So, let me give you a little scenario... You're in your bedroom, it's 11PM and night, and you really wanna' get laid. (Honestly you shouldn't be praying for that if you are of Christain faith).
So you pray to god, "Dear god, almighty, all-powerful, all-loving creator of the universe, I pray to you to get me laid this Friday night, I really do not want to be embarrased in front of all of my friends. Please, make me wake up with a massive sclong (preferably about 12 inches), thanks, John."
I can bet any amount of money, and win. Win the bet, that you will most probably not get laid on Friday night, (simply because you're faithful to god (notice the non capitalisation)). and because you're a loser. Second of all, you won't wake up with a massive sclong, simply because you are Asian.
My second argument is "mircales". Notice what happens when anyone is "miraculously cured". A person is sick, the person prays (or a prayer circle prays for the person) and the person is cured. A religious person looks at it and says, "God performed a miracle because of prayer!" That is the end of it.
A scientist looks at it in a very different way. A scientist looks at it and says, "Prayer had nothing to do with it - there is a natural cause for what we see here. If we understand the natural cause, then we can heal many more people suffering from the same condition."
In other words, it is only by assuming that God is imaginary that science can proceed. If God was real, why would we need science. God could do it all for us!
Third argument, is how useless the world is. Look around you, (yes, you, the stupid Ethopian who has a cheap laptop with Dial-up internet). Look at Africa, look at the poverty. As far as I know, God wanted a good life for everybody. Unless this is Adam & Eves fault, (in which case blame those two stupid fuckwits) for eating the apple off the tree. If God was real, I'm sure there would be a balance between life, I'm sure black people would have money, I'm sure everybody would enjoy a nice curry (not just the Indians), and I'm sure that people in Africa would have clean water to drink (not water that looks like the shit you just took), as well as them having food, and not getting raped by lions on a daily basis. (Just like your Dad is going to do you to tonight, (Yes, he's a lion.))
TL;DR. God is not real, everybody who beleives in him is stupid & foolish. (Religion is honestly the biggest hoax ever pulled). If you pray @ night, you're not going to wake up with a massive schlong and hair on your balls And also, science is the way to go. If god is real, why are people dying of starvation in Africa, why does your Mum have a beard, and why are you still a virgin after 40 years of trying & failing.
