A "religion" is a belief in God (called different names depending on the religion, such as 'Allah' for Muslims), and those are the ones who believe there is an eternal afterlife with God after death. Those who believe "when you're dead you're dead" are atheists and do not believe in God. And since Atheism is not a religion, there are no religions that fit the definition of your question.
There is no scientific evidence to indicate they do or can. However, many religions believe this to be the case.
This is an interesting question. Many religions honor their dead with funeral services or rites. I believe that most of these traditions started more as an honor to the God that they served. Similar to an offering of sorts. Honoring the God by giving them the spirit of their dead. Please their God and their loved one will get to enter the afterlife. Some religions, like the Buddhist I believe, use chanting by monks to guide the spirits of the dead through the temptations of a sort of pergatory and into their next reincarnate life. Some religions, mostly of the less civilized tribes and cultures, perform ceremonies to appease the dead in fear that the dead might come back to haunt or curse them. Some religions believed in preserving the dead so that their bodies could be used in the afterlife. I think most religions, be it earthen burial, sky burial or cremation believe that the body is a shell for a spirit which has passed on and should be returned to the earth from which it came.
Dead people don't work or do anything. They are dead.
no
Catholics remember and pray for those who "Sleep in Christ" (those who believe) and are waiting for God to bring them to heaven.
There is no definitive answer to whether the dead pray for the living, as beliefs and interpretations vary among different cultures and religions. Some believe that the dead can intercede on behalf of the living, while others believe that the dead are at rest and do not have the ability to pray. Ultimately, this is a question that is open to personal interpretation and faith.
Many religions believe in the existence of spirits of the dead, often seen as souls that continue to exist in a different realm after physical death. These beliefs vary widely among different cultures and religions, with practices like ancestor worship, communication with spirits, and rituals to honor and remember the deceased being common themes.
yes they did that's why they embalmed their dead bodies , so when they wake up their bodies will be still the same.
This depends on your perspective, if you are referring to Jesus of the Christian Bible: all Christians believe so. As of our day, we have yet to prove that humans can come back from the dead.
you can not
In some religions they can
No, not all religions believe in a "purgatory". Some believe in just a Heaven and Hell and some don't even believe in that. The Baha'i Faith teaches that Heaven and Hell are spiritual states or conditions that one's soul attains as a result of that persons actions and attitude in this life. One does not have to be physically dead to be in Heaven - near to God, or Hell - distant from God.
