Here is an excerpt

"Conventional wisdom holds that the first stars were born of the hydrogen and helium present in the early universe."

Answer 2

Since primordial nucleosynthesis produced only three elements - H, He, and Li - it is widely accepted that the earliest stars must have formed from the gravitational collapse of couds rich in H and He, and the thermonuclear fusion that now dominates the Sun's energy output (the formation of He from H in the proton-proton chain) was also the way that these early stars produced their energy.

Answer 3

Hydrogen.

A star is a fusion reactor which CREATES Helium by fusing Hydrogen atoms together. The energy (light) comes from the release of excess energy when the atoms are fused together.

Answer 4

Hydrogen and Helium, like the closest star to Earth, the Sun.
