This is confidently incorrect. If you're making observations of very short-lived processes your margin of error will be in micro-, nano-, atto-seconds etc. If you're looking at processes that take billions of years, naturally the margin will be wider, especially that it's very hard to make accurate observations about stuff that took place a very long time ago. It's not that hard to grasp.
