FWIU in Grand Traverse Bay, Lake Michigan, there's a 9,000 year old stonehenge-like structure 40 feet underwater; that's 4000 thousand years older than Stonehenge and about 6000 years older than the Osireoin and the Pyramids.

There's not even a name or a wikipedia page for the site? There are various presumed Clovis sites which are now underwater in TN, as well.
Calling it Stonehenge-like is a real stretch.

If you can just roll up to the pump and communicate with it over Bluetooth, then I'd argue that it's a design flaw and the manufacturer should be held accountable as this seems like a gross laps in security.
A hydrogen planet would be particularly easy, since the light molecules would maximize Isp for a (non-combustion) thermal engine. A nuclear scramjet on a Hycaean world would have some truly impressive performance.
So yes, you eventually evolved for this, but it wasn’t the dominant food source for a loooooong time.
