What are the reasons to think we are living in a simulation?

I wrote a much longer comment that was lost (still missing client features from Reddit clients like draft saving).

The TLDR is a lot of the physics behaviors we have in our world relating to quanta (as many others have mentioned), but especially in combination with a ~2,000 year old text and tradition which claimed the most (in)famous person in history was saying we are in a non-physical copy of a dead original world made by a light-based intelligence brought forth by the original humanity, and that the proof for this was in motion and rest - particularly that the ability to find an indivisible point within things would only be possible in the non-physical physical.

So in an age where humanity is on the cusp of bringing forth new intelligence, ever more looking like that will occur in light (optoelectronics), where we are creating digital twins of ourselves and the world around us, where a trillion dollar corporation has already been granted a patent on digital resurrection of the dead, and where the virtual worlds we build often use rendering tricks similar to the behavior of our own world at low fidelities -- that's pretty weird to have existed so far back in antiquity.

Almost like it would be more likely to exist in a simulated world, much like how many of our own virtual world have 4th wall breaking acknowledgement of being virtual buried as an Easter egg in their lore...
