Greetings,

i thing more important than the question
"is a religion true" is the question:
What have this religion bought to the poeple ?
How much genocide ? And on the other hand side :
How much better are people who have a bad life by having this religion ?

Imagine you were a poor farmer in medival times, how much better would your life be if you (belive) to know for sure
that sometimes later(after dead) you will be very happy ... ?

In fact, a lot of religions have bought genocide to people,
i don't know much enough about islam,
but our christian religion bought us the crusades,
and it set a lot of people alite who had other believes ...

nowadays, the easiest way to decide might be to look at the people who are religious ...
the ones who are feeling loved by an almighty entity look very calm and happy ... but the ones who feel watched and controlled from a cold god, or even feeling hell,
are feeling like theyare only worthless sinners ... poor people, in my opinion.

I won't propagate for a special religion here,
as i told: everyone should judge for himself,
these are only some ideas ;-)
