10 Most Messed Up Deaths In Star Trek: The Next Generation
7. Miller-Urey(-Q), Who? — All Life On Earth
When doctoral candidate Stanley Miller and supervisor Harold Urey were running their famous experiment that set out to reproduce the atmospheric conditions thought to have existed on Earth between 4 and 3.5 billion years ago (the 'primordial soup'), in order to demonstrate that organic molecules (such as amino acids) could indeed be produced from inorganic compounds in such an environment, they weren't counting on an anti-time eruption as a factor for the chemistry.
When Q transported Picard back to his "[extremely] old stomping grounds" in All Good Things… however, whilst there were already amino acids present on that prebiotic Earth, they had been stopped short of forming the first protein by the anomaly. There's the 'everyone dies and then comes back to life' messed-up, and then there's the All Good Things… 'every animal, plant, fungus, protist, archaeon, bacterium, and virus will never have existed on Earth in the first place' kind of messed-up!
It is estimated that, as of 2022, the number of humans to ever have lived was in the order of 117 billion, and who knows how many more by the 24th century (and beyond)! Plus, in the far-far-far-distant-past, the anti-time anomaly, which Picard had technically created with the convergence of three inverse tachyon pulses, filled the entire Alpha Quadrant. That's a whole lot of extra effed-up non-existence before Jean-Luc was able to figure it all out!
