How so? The 0°-100° era was between 10 and 17 million years after the Big Bang. There were no stars or planets during this period. There were no primordial elements heavier than lithium. Heavier elements were not created until several hundred million years later, after the first supernovas. "At some point around 200 to 500 million years, the earliest generations of stars and galaxies form" -- Before that, there were no oxygen atoms.
