How come there seems to be mostly Atheists on here in the religion section?

Most the people here in the religion section are atheists. I have seen a few Christians on here but not many. I know the bible says that only 133,000 people only will end up making it to heaven and that is sad. This is an extremely small number compared to the population of the world witch is 6.91 billion. Also you would have to consider the population of the rest of the world from the people that were here before but ped away. This number of 133,0000 is way less than the population of just Chicago, Illinois alone. I don't want to offend anyone but this saddens me deeply. I want everyone to be saved. Please answer my question politely and not sarcastically.
