It's a game with no end.

There is no ultimate truth, and that's not a problem for me as I'm agnostic.

Let's say that we all wake up one morning and we all have a popup box in our field of view reading "you are in a simulation".

Would we all discover any truth...?  no, there will always be more questions... do the creators of our sim exist in a higher sim, or are they "real" etc. steps would have to be taken to determine possible causes for the shared popup, was it some weird virus dropped by ETs etc.

Only an egotistical fool would think they could find ultimate truth either way. Everybody should apply the best-fit solution to their own perceptions. But it does puzzle me how many theists sit like stubborn toddlers trying to push a square peg in a round hole, still if that pleases them then so be it.

I also note that those with polarized minds (theist and atheist) tend to stop researching and playing. Once they've labelled the box it gets shut, after that their faces drop a little and they become "adults", me I'm a 42 year old boy, I try to hold the same awe when I view the stars as when I was 10. I guess a simple term for agnostic is "keeping an open mind".
