David Hayward draws the truth: Ultimately, we all just end up in the same place.
The different is that atheists are honest about what happens when we all die. We don’t make up stories about the afterlife. We don’t claim to have knowledge about something no one has ever experienced. We accept that death is the end of the line and hopefully we’ve left behind wonderful memories and a positive legacy for those around us.
Side note #1: One of the commenters on David’s site alludes to this, but does it make sense for an atheist to have “Rest In Peace” written on the tombstone? There’s obviously no need to worry about that.
Side note #2: Tombstone? What a waste of space. Atheists ought to be giving their bodies to science or being cremated. (Sure, they’re not around to make that decision, but they can let others know of their wishes beforehand.) Are others with me on this?
Side note #3: You’re all organ donors, right?
