However, according to some religious beliefs, people in heaven are said to have a perfect and eternal memory, which would allow them to remember what happened on earth.
In Christianity, for example, the Bible states that people in heaven will be aware of what is happening on earth. In the book of Revelation, it describes the souls of martyrs who are crying out for God to avenge their deaths and it also mentions that there will be a great reunion of those who have died and are now in heaven.
In Islam, it is believed that people in paradise will have knowledge of their earthly lives but will not feel sorrow or regret for the things that they did not achieve or experience.
In general, different religions and belief systems have varying perspectives on the nature of heaven and the afterlife, so it is best to consult the teachings and traditions of your particular faith to understand what it says about this topic.
