According to the 2012 WIN-Gallop Global Index of Religiosity and Atheism 87% of the world’s population believes in a god.
Now, according to the World Health Organization 8.2 million people die each year worldwide due to cancer.
Based on these statistics we can make the assumption that 87% of these cancer deaths were brought upon believers.
That means 7.13 million people (.87 * 8.2) who believe in god die of cancer each year.
God is omnipotent and all-knowing, an intelligent designer. Using that intelligence, god created cancer. It’s anybody’s guess as to why, but don’t question it.
According to acceptable sources the definition of carcinogen is: A cancer-causing substance or agent.
Therefore, god (as agent) is the world’s leading carcinogen with 7.13 million deaths per year.
Tobacco use, coming in at a far second place, accounts for 1.13 million cancer deaths per year. (71% of the 1.59 million lung cancer deaths per year according to the WHO.)
That means a belief in god causes over 6 times the number of cancer deaths as tobacco use.
In other words, light ‘em up! Cigarettes have nothing on god.
