When space-time itself is expanding, light just gets carried along for the ride.
All of this stuff seems completely bogus, but the predictions based on it play out in the best observations made to date. Even if it isn't 100% correct, it's the best we've been able to do so far... and it's mind-blowing.

The universe explodes. All of it’s energy is focussed on this singular act of creation, and it grows at a rate that has no parallel in our existence. During the first few seconds, there is nothing that we would recognize as matter yet. Space literally seethes with energy. This energy is carried by particles that we consider the elementary building blocks – quarks and leptons – and by particles that are responsible for the four forces that we see at play today. As the universe expands, it cools. After a few years, more complicated particles such as protons and neutrons begin to exist. Sometime later, maybe several thousand years, the universe has cooled further so that atoms can form. First the very simplest, hydrogen, made up of jus two particles. Later, heavier elements are created. And even later still, more complicated structures begin to form through the force of gravity. This is the “big bang,” and history – at least the timeline that we are following – has started.
INFLATION ERA
The universe
undergoes a brief,
explosive period of
inflation, growing
from smaller than an
atom to the size of a
grapefruit. The
inflationary
expansion stops
when the force
driving it is
transformed into
matter and energy
as we know them

The energy was always there, it never had a begging since you can not create or destroy it. The big bang, if it did happen, could of been concentrated energy much greater than light. And that is still moving faster than light which than becomes a dense nothing called optimum matter, which is matter that is nothing but when slowed down it then becomes light and heat and other phenomenons.

as per what einstien proposed space and time are related to each other. at the time of big bang the space was expanding. we must know the space is made up of dark energy. therefore energy was expanding. that implies time was shrinking. if we take a fixed distance x and divide it by the time taken by light to cover x now(Tn) and the time taken by light to cover x just after big bang(Tb) we get the velocities if v is velocity just after bb vxTb=cxTn solving we get
v=cx(Tn/Tb)
Tb is less than Tn so V is greater than C.
so Speed of light was more at that time.

a nonsensical question. we are but a speck in a gigantic cosmos in a small fraction of time, if u believe the universe to be 10 billion yrs. old, and yet u and your ilk are audacious enough to believe that u can acutallly ask questions like this even given that we see stars and formulate doppler theory on things and events that happened billions of years ago. I think not.

The speed of light probably hadn't been established yet. In other words, light itself was probably traveling faster than it does now.

Because that's what the inflationary theory dictates. And a full-bloodied scientist would first trust his equations rather than his common sense.

Do not believe in fairy tales. The universe was always there.
Why should it have been born? It is not a man or animal!
