Light has always been, it's simply a form of energy - like heat energy, kinetic energy, etc. Scientifically speaking, you cannot remove energy, only change it, so in a sense there is no beginning and no end to light.
God said "Let there be Light" and the universe magically appeared out of nowhere.

When the big bang theory started the universe, light was created.
Light is not the origin of the universe. The universe began with the Big Bang, a rapid expansion of space and time. Light is a form of electromagnetic radiation that was produced after the Big Bang as the universe cooled down and matter began to form.
WHY does light have a dual character? As far as we can tell, in our Universe, it just DOES. There's nothing about our Universe that would require that light sometimes behaves like a particle, but, whether we like it or not, in our Universe it does.
Yes, light can travel forever in the universe unless it is absorbed or scattered by objects in its path.
The universe's primary source of light is stars. Stars are massive balls of gas that undergo nuclear fusion, generating heat and light that radiates out into space. Other sources of light in the universe include galaxies, quasars, and other celestial objects.
Tachyons are theorised to be the fastest particle in the universe their slowest speed being the speed of light. But until they are proven to exist, light is the fastest thing in the universe.
Every point in the universe is lighted by stars.
universe's equator distance is about 150,000,000,000 light years.
A light beam that travels for the entire lifetime of the universe would cover a distance of approximately 13.8 billion light-years. This is because the observable universe is estimated to be about 13.8 billion years old in terms of light-travel distance.
Light is not infinite in the universe. While light travels at a very fast speed, it can still be absorbed or blocked by objects in space. Additionally, the universe itself is constantly expanding, which means that light from distant sources may never reach us.
