Because there is overwhelming evidence for the universe and a huge amount of evidence that there are no such things as gods!!
Academia states that in the absence of proof of the existence of something it must be deemed not to exist until verifiable proof is found - thus god is held not to exist pending some sort of verifiable evidence.
There is not one single mention of Jesus in the entire Roman record - that is right - not one!!! At the same time as he was supposed to have been around there were a number of Jews claiming to be the messiah - all of whom are well recorded!!
There is not a single contemporary record from any source and even the bible mentions of him like all other references were not written until many years after his supposed death!!
He was supposed to have been a huge problem to the Romans and produced wonderful miracles but still not one contemporary record?
Even the bible mentions of him like all other references were not written until many years after his supposed death!!
Pilate is recorded in the Roman record as a somewhat lack luster man but no mention of a Jesus, a trial or crucifixion that would surely have been used to make him look brighter!!
At best he was an amalgam of those others!!
The Roman Emperor Constantine produced the bible and he was a pagan not god!!! He also organized Christianity into the Holly Roman Catholic Church!! Not in Israel or any of the countries of supposed origin but entirely ITALIAN!!
Not one word of it is contemporary with the period and was not written until several hundred years after the period the story is set in!! How did the apostles write their books more than a hundred years after they would have been dead?
What a wonder full disinformation and deception campaign he waged against his Christian enemies - so good in fact that Christians are still following the deception to this day!!!
The first person to provide a shred of verifiable evidence for God will become world famous and mega rich!! Ain't happened yet and it never will!!
So how does this primitive belief survive? The answer is simple and very down to Earth!!
Acceptance of a supernatural claim tends to promote cooperative social relationships. This communication demonstrates a willingness to accept, without skepticism, the influence of the speaker in a way similar to a child's acceptance of the influence of a parent. By encouraging this kind of behavior where the most intense social relationships occur it facilitates the lack of skepticism and deters more open minded thinking.
They are christian, Muslim or the other religions depending where they were born simply because they were indoctrinated by their parents as very young children. They will go on to indoctrinate their own children and those will go on to indoctrinate their grandchildren!!
Atheists have the intellect to see through the conditioning and escape into the real world!!
Agnostics have the intellect to see through the conditioning but lack the courage to throw of the conditioning entirely.
Sadly Christians are still held firmly prisoner by the self perpetuating brainwashing!!
