A while a go i had a good topic about this. from the atheist perspective. unfortunately i cannot find my original thread so i will try to work my argument from memory.
Here is why god does not exist.
PART I
religion is a constant. every civilization that has come up through time has had a deity or deity's of some sort that they have been described to have similar uniform traits. omnipotent and omnipresent tend to be the two most common for monotheistic societies. strong mortal like patriarchal characteristics show up in polytheistic societies. These polytheistic gods remove the omnipresent and omnipotent factor that a single god would have to deal with by having specific jobs (god of war, god of feast, god of ...). so what dose all this leave us with. it leaves us with one question. of all the gods hat have popped up through history, who was right?
The Christian god?
The Muslim god?
The Greek gods?
The Aztek gods?
Early Asian supernatural beings?
...
its uncertain.
Now the smart christian will acknowledge that, well our god (father of christ) is obviously the only true god because we the dominant religion. well first you are not the dominant religion, Islam is (may bee Hinduism I'm not 100% sure). and second even if you were the dominant religion it is only so because white Anglo Sxon christians wared and superimposed their chritian religion to less advanced people.
Your not right on having chosen the right god, your only right because you have won through war murder and violence, (which by the way is unwanted by commandment number 6).
finally because my memory is fading on what i had written before. if god is truly all mighty, then why make humans? if something is eternal like the promise of life after death then it had no finite beginning or end. if something has no beginning or end then it does not exist. so here i have disprove the sole reason for religion, which to provide something to look forward to after death (come on your a "good" Christian so that you can be accepted in to gods kingdom after death). well if that kingdom is eternal and eternal things do not exist, then there is no promise of life aster death, which means that there is no "gods kingdom" which means that there is no god.
Finally (and this is not rhetorical i WANT an answer) why would god create a begin who could think for itself and in the process conclude through the logic that was given to it by go, which was modeled after the logic of god,logic that there in fact is no god?
in the end i want you to do this. For 1 hour, think for your self, do not use any preimposed idea that has been infused into your brain by your religion, and explain why a tree looks the way a tree dose. i promise you that you will come to an answer more magnificent than "because god designed it that way".
i want you to realize that i am not trying to "diss" your god or say that you are wrong. i just want you to stop thinking in the religious collective you are part of, and start thinking for yourself.
