The best scientific estimate right now is between 15 and 17 billion years ago, with most astrophysicists favoring the lower number.
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.
It began to expand in size. There is a hole at that point in our knowledge of the early universe but without a doubt the universe began to expand.

Sub-atomic particles of matter and anti-matter, that all clumped/combined to form various things... That is the best I can describe it...
The origin of the universe is just that - a theory. We can only speculate how universe began - based on the knowledge we have up to now. There may be other factors - that could change our perspective on how the universe began - yet to be discovered !
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
The universe began approximately 13.7 billion years ago. The big bang theory describes how the universe was created, and began to expand rather rapidly.

We do not know how the universe began, or what the exact sequence of events were.
The existence of things in the universe is a complex question that scientists and philosophers have been exploring for centuries. One theory is that the universe began with a big bang, leading to the formation of matter and energy. Another theory is that the universe has always existed in some form. Ultimately, the exact reason for the existence of things in the universe remains a topic of ongoing research and debate.
Islam began by; and even; before universe creation. Refer to question below.
