It's not so much about believing in coincidences; rather, it's about considering all possible variables. The sudden and substantial rise in recorded CO2 levels could be attributed to advancements in measurement techniques and the increased frequency of those measurements. If we had access to the same level of precision and quantity of data 500 years ago, it's plausible that we might have observed similar CO2 levels. Looking at the "Last 800,000 years" chart, one can observe many sudden spikes throughout the history, meaning the current "sudden spike" could be nothing but the organic state of the planet.
