Does heaven exist?

Although many religions teach of an afterlife called Heaven, there is no direct evidence to prove a heaven actually exists. The idea of giving a location to the afterlife is a popular religious tradition.

According to Christian doctrine, Heaven is not necessarily a place, but the idea that the deceased person regains what he or she has lost. Although religions that preach of a heaven label it as the place "good" people go, there is debate within those religions about what defines being good. However, sub-sects of the Christian religion have different standards that must be met, such as believing in Jesus Christ or having last rites performed.
