the first stars formed when the Universe was only about 200 million years old. Observations by WMAP also revealed that the Universe is currently about 13. 7 billion years old. So it was very early in the time after the Big Bang explosion that stars formed.
Observations reveal that tiny clumps of matter formed in the baby Universe; to WMAP, these clumps are seen as tiny temperatures differences of less than one-millionth of a degree. Gravity then pulled in more matter from areas of lower density and the clumps grew. After about 200 million years of this clumping, there was enough matter in one place that the temperature got high enough for nuclear fusion to begin - providing the engine for stars to glow.
This result surprised many scientists who thought that it would have taken much longer for gravity to pull enough matter together to make a star.

Assuming the Big Bang Theory to be true, there was a lot of spare matter (almost entirely hydrogen) floating around in the universe. Gravity made the hydrogen collect, and, like it all other things, form a sphere of gas. Eventually gravity forced these spheres to collide and coalesce. A few million years later, there was enough matter for the balls of hydrogen to cause the necessary pressure for nuclear fusion, which resulted in the formation of a glowing star. These stars, influenced by their on gravity, collected together, and with the additional gravity of other, more mysterious forms of matter (such as dark matter) the stars formed galaxies.

Oh Drat...I missed it... How did that happen?
I did not hear the names of the first stars. is that written in a book somewhere?
I did not hear the names of the first galaxies. Is that also written in a book somewhere?
OOOOOOOooooo you wish to know how they came into existance? As in the beginning? Well now... let me just turn around to some of the other fellas here at the Bar and ask them how it all began....
Keep in mind that nobody was alive in the beginning, and they didn't get books, and pencil and paper till just a wee bit ago.

To be sure, no one on this planet can say with any degree of certainty.
However, more than a few scientists and astronomers speculate that the universe is between 11.2 and 20 billion years old.
The theory is that some kind of cosmic 'big bang' created the stars, dust and subsequent galaxies.
Scientists use a predetermined measuring unit to understand the complexity, age and expansion rate of the universe.

When God seed let there be light, there was a massive blast of energy, and from this blast of gas and other items the Universe started to form, it would take a long time to describe step by step how every thing took place.
But here is something for you to think about.
It took God six days to create the heavens and Earth, but as the Earth did not exist yet then these six days were not Earth days.
A billion years to us is only about a day in Gods time.
If you go by Galactic time and you live to be a hundred years old, in Galactic time you have only lived one one millionth of a mile second.

No one has the correct answer here or anywhere for now it is all speculation and theory's...
