We're they created with the knowledge of how to use fire?
If they not, did they learn it later (some time after creation)? How did their offspring learn how to use fire, assuming they did?
Mitochondria Eve and Y-Chromosomal Adam lived some few hundred thousand years ago.

"By definition, it is not necessary that the Y-MRCA and the mt-MRCA should have lived at the same time.
[ While estimates as of 2014 suggested the possibility that the two individuals may well have been roughly contemporaneous, the discovery of archaic Y-haplogroup has pushed back the estimated age of the Y-MRCA beyond the most likely age of the mt-MRCA. As of 2015, estimates of the age of the Y-MRCA range around 200,000 to 300,000 years ago, roughly consistent with the emergence of
anatomically modern humans.

PMID 25770088. "we date the Y-chromosomal most recent common ancestor (MRCA) in Africa at 254 (95% CI 192–307) kya and detect a cluster of major non-African founder haplogroups in a narrow time interval at 47–52 kya, consistent with a rapid initial colonization model of Eurasia and Oceania after the out-of-Africa bottleneck. In contrast to demographic reconstructions based on mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky. We hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males."

Ash from wood burnt as controlled use of fire by a being of a homo genus species has been dated to have occurred roughly 1 million years ago.

In conclusion, Mitochondrial Eve and Y Chromosomal Adam likely lived some few dozen thousands of generations following the earliest use of fire by a being of a homo genus species.
