What if everything in the past has been a long string of coincidences. Where we observe and infer the law of gravity it is just a coincidence that all those times stuff fell down. Balls flying through the air could have turned left, but they always happened to go straight. All natural laws could just be a highly improbable string of events.

In an entirely different but similar fiction:
Our universe appears to be free of contradictions. What if the many worlds hypothesis were true and there are often branches where some inherent contradiction occurs. These collapse/explode/disappear as the they occur and by the anthropological principal we only see consistent branches.
