The 3 properties that God has, according to Scripture, is that he is omnipotent, i.e. can do everything, he is omniscient, i.e. he knows everything, and he is omnipresent, i.e. he is everywhere.
Logic (of the mathematical kind :-)) says the above cannot exist, because it is contradictory to itself.
If a being is omnipotent, then it certainly can create something stronger than itself, can it? But then it is not omnipotent. But if it cannot create something stronger than itself, then it is also not omnipotent.
If a being is omniscient, then it certainly knows every person's future, and hence our future is prewritten, and so it is also prewritten if we are good and go to heaven or bad and go to hell. But the scripture also says we should try to be good...but if the future is predetermined, the word 'try' is completely meaningless.
If a being is omnipresent, can it create anything? If it can, then it is not omnipresent, because there was free space for creation. If it cannot create anything, then it is not omnipotent.
The above might sound like wordplay, but it is not. It is actually math disguised as wordplay. It is math that talks about sets and infinity. And it is indisputable mathematical proof that there cannot be an omniscient, omnipotent and omnipresent God.
