First, people made a lot of damage, not religion.
Second, a lot people, inspired by faith, did many great things for humanity like serving the poor, ill, homeless people etc.They even opened the hospitals, schools, started charities...[/quote]
These two comments are the reality of Religion. It's not the religion that kills people, it's the people that kill people (and if they do so "in the name of [religion]" they are completely misinterpreting what their religion is preaching.
Lastly, if man created religion, it will disappear.
If God created religion, it will last forever.
I struggle with this bit...which answer is it? How will we ever know? Additionally, most religions say they expect a regular attendance at a house of worship, however religion itself doesn't necessarily require this. To believe in religion and follow religious principles requires least of all the regular attendance to a mosque, synagogue, or church. SO while these visual elements of a religion may grow or decline it's not indicative of the actual belief and faith people have from one community to the next.
