Quizplus · Accepted Answer

During the era of nucleosynthesis, hydrogen and helium were formed along with trace amounts of deuterium and lithium. This is supported by observations of the cosmic microwave background radiation, which reveals a pattern of light elements consistent with this theory. The formation of heavier elements would occur later through the process of stellar fusion.
