What is a "God"?

I noticed in the past few years a general increase in the number of games that revolve around Gods. In certain cases, this involves killing a god - God Of War involves having Kratos kill Ares, the Greek god of war.

So I thought about the whole idea of what is a "god" and how "mortal" they appear to be. The most illogical aspect that I have discovered so far is people's inability to distinguish the difference between mortals and imortals. Assuming we run along the basis of the Greek Gods, they ruled over the Greeks during the pre-roman empire section of history. A large number of texts point towards the idea that the gods looked down at the humans, referring multiple times to how they are "mortals".

While this is painstakingly true (After all, they are human), it gives reason to say that because they call Humans mortals, and they are so much more powerful than humans, they therefore should logically be immortal. Considering how aledgedly have the power to modify the fabric of reality itself, they might as well in all true sense have the power of immortality.

So, if we compare the differences between "mortals" and "immortals", the notable differences are quickly made apparent. Mortals don't live forever, Immortals do. If an Immortal has the ability to live forever, it stands to reason that they can't simply be hacked to death. The logic of immortality prevents them from becoming deceased (The concept of pain however is a different story). While it probably would be painful having their head cut off and still not dying, it simply makes no sense that severed limbs should kill an "immortal".

Though, there is a work around if your willing to go that deep. Many "lesser" Gods are referred to as semi-imortal. A.K.A: They don't grow old and die, but they can be killed by getting chopped to pieces. However this still brings up problems. "Less" and "God" are two words that DONT go together. The concept of Godhood means all powerful. If you add "less" or "demi" as a prefix, your essentially saying that this "god" is all powerful, but also not.

Ah, but what if we change the definition of "God" to not being all powerful? Make the definition of God something close to almost all powerful but not quite. This is all just a convenience plot twist. It just doesn't work because a God is a God. The definition of a God is all powerful. You can't change that.

It's almost like saying that Coke is pure water. I'd certainly raise an eyebrow to a statement like that.

And that's why I believe in my God - The great big holy christian God. Because he's all powerful, omnisienct, and thats the end of that. You cant fight who he is, because he's immortal and your not.
