Not 100% but you can get a reasonable idea but looking. The God hypothesis seems unlikely for a variety of reasons such as the presence of evil and why there are trillions of stars if it was made for us.
Simulations are normally quite imperfect - you can see the pixels etc. The physics of our universe is hard to simulate - we can't even do one proton reasonably well yet no glitches are seen in physics experiments so that hypothesis seems unlikely too.
Personally I think it's maths. The deeper in physics you go the more it looks like maths. See https://www.amazon.co.uk/Our-Mathematical-Universe-Ultimate-... for example.
