I can get that we may have created something (quark-gluon plasma) at 4 trillion degrees Celsius that is hotter than a supernova, but…
How could we have created the coldest thing ever, at 100pK (less than 1 K), and that there is nothing colder? Might a single atom in deep space not have less energy? Apparently some nebula is the coldest thing out there.

You cannot actually say a single atom has “temperature” really.
“Temperature” is really the measure of the average energy over a bunch of matter. If all you have is one atom you don’t even have “temperature” to measure or experience. Not the same as saying “zero” as a temperature just to be clear.
