Life After Death Wiki

why must there be such imagination about life after people while there are always 2 birth for 1 death? – wikipedia

For the same reason that there is such massive speculation about life after death. It’s the unknown. Humans are so centered on their own condition, their own existence, that they rarely take time to think about the entire cycle of life on this one small planet. Using the imagination, well, that’s a humans best gift, isn’t it? The ability to imagine.
Put the two together, and there is endless speculation about those things that can have no concrete proof…life after death, God, and now, life after people.
