Helium is formed by nuclear fusion reactions between hydrogen atoms under extreme temperature and pressures. These reactions still take place today in the centers of stars; in fact, the enormous energy released by such reactions is what drives our own sun.

How might the objects found in the early universe differ from the objects found in the universe now?
In the early universe there was only Hydrogen and Helium (and a smidgen of Lithium).
What is helium natural occurrence?
about 23% in the universe.
Where did hydrogen and helium in the universe come from?

Was Early in its history the universe was 100 percent Hydrogen H and Helium He?
Different theory prevail but the leading one states that at the initial formation of the Universe it was just 100% hydrogen. A few minutes later, the universe had cooled to about one billion kelvin and nuclear fusion occurred, this lasted only a few minutes but was rapid enough to produce the ~25% Helium we still see today. There was also a little bit of deuterium and lithium but generally, a few minutes after the big bang the Universe was 75% hydrogen and 25% helium.
What are the things that make the universe?
The vast majority of matter in the universe is in the form of Hydrogen and Helium.
How might the objects found in the early universe differ from the objects found in the universe now?
In the early universe there was only Hydrogen and Helium (and a smidgen of Lithium).
Judging from the abundance of stars in the universe where does most of the hydrogen and helium come from?
From stars.
What are all of the gas giants atmosphere made up of?
Mainly hydrogen and helium - which were also the main elements in the early Universe.
What country is helium from?
The USA produces about 80% of the world's Helium . It is the second most abundant element in the Universe. When the singularity that preceded the universe erupted in what we call 'The Big Bang', hydrogen particles began to form, and from these helium resulted in the nuclear furnaces of the early stars. Most of Earth's Helium is the result of radioactive decay, originating in the long run from the core of the Earth. There is a good article on Helium in wikipedia.
How plentiful is helium?
Helium is the second most plentiful element in the universe.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
Why is it likely that life did not form during the very early history of the universe?
In the early Universe, there were no heavy elements around - all the matter of the Universe was in the form of hydrogen, helium, and small amounts of lithium; until the first stars formed, created these heavier elements, and put them out into space when they exploded as supernovae.
What percentage of atoms in the universe are helium?
94%
What is helium natural occurrence?
about 23% in the universe.
How long has helium been in existence?
Helium is has been in existence since the beginning of the universe.
