You disregard religion as if religion is totally against science, The very first scientists were actually muslim just to inform you.
- do you have any idea what happens when you die? You dont. your answer is" no body knows. Every one just has their own beliefs".
If you are right about there being no heaven or hell and religion is just a big lie.....a religious person(I'm Muslim) would still have no problems. they would just rot in the ground when they die just like you. But they will benefit from all religion has taught them when they where alive.(E.g. a muslim will be free from the 5 poisons of society: Drugs, Alcohol, Sexual Immorality, Gambling,Interest Dealings)
However If religion is correct about Heaven and Hell, And it really does exist.....then you could be in real trouble.
So dont be trying to make fun of religion, when you cannot prove that Religion is a lie, Not even Einstein was able to do that. What Prophet muhammed did. P.B.U.H and Jesus.P.B.U.H did has benefited billions over the world and will save us in the afterlife.
