Our Universe had a beginning and therefore will have an end.
It consists of three things - energy, matter, and life.
The first two are interchangeable, the third is beyond the grasp of science.
The scientific community was once divided between supporters of two different theories, the Big Bang (scoffed into existence by Fred Hoyle himself) and the Steady State theory of Fred Hoyle, but a wide range of empirical evidence has strongly favored the Big Bang which is now universally accepted.
We first grasped the universe had a beginning in 1927 when Georges Lemaître first noted that an expanding universe could be traced back in time to an originating single point. Scientists have since built on his idea of cosmic expansion. In 1929, from analysis of galactic red-shifts, Edwin Hubble concluded that galaxies are drifting apart; this is important observational evidence for an expanding universe.
In 1964, the cosmic microwave background radiation was discovered, which was crucial evidence in favor of the hot Big Bang model, since that theory predicted the existence of background radiation throughout the universe before it was discovered.
The known physical laws of nature can be used to calculate the characteristics of the universe in detail back in time to an initial state of extreme density and temperature. Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered to be the beginning of the universe.
They back-tracked to a single point in time and labeled it a "Singularity," BUT how did everything come out of nothing?
Lucky for our understanding, there are other singularities in our universe nicknamed "Black Holes." The more we understand about them, the better we understand where Our Present Universe came from.
My understanding is that the previous universe had the same beginning as ours did, went through the same processes this one is -
An Event Horizon as envisioned by John Mitchell, within which Huge masses of energy created internal black holes that become surrounded with even larger clouds of Hydrogen and Helium that become the first stars and galaxies, then produced myriads of supernovas that transformed energy and mass into ever more complex elements in an expanding universe that finally reversed and ended in a "Big Crunch" of a final black hole that was our big bang, and THAT is where everything came from.
Unfortunately that answer puts off the question of the original creation of everything.
For OUR Present life cycle the work was organizing elements spewed from novas and supernovas into suitable planets with the "Goldilocks" locations and sizes and contents of Not to hot, not too cold, not too big, not too small, all the needed elements joined int o all the needed minerals for life to exist.
Here it took 13.8 billion years to get to that point. then guiding life to release enough oxygen so life could exist on land, join the dna of worms to become the guts of higher life forms, build an appropriate food chain, prepare for the placement of MAN.

If there should really exist in nature any bodies, whose density is not less than that of the sun, and whose diameters are more than 500 times the diameter of the sun, since their light could not arrive at us; or if there should exist any other bodies of a somewhat smaller size, which are not naturally luminous; of the existence of bodies under either of these circumstances, we could have no information from sight; yet, if any other luminous bodies should happen to revolve about them we might still perhaps from the motions of these revolving bodies infer the existence of the central ones with some degree of probability, as this might afford a clue to some of the apparent irregularities of the revolving bodies, which would not be easily explicable on any other hypothesis; but as the consequences of such a supposition are very obvious, and the consideration of them somewhat beside my present purpose, I shall not prosecute them any further.
