All the matter in the universe was created in the "big bang", therefore, it NOW can't be created nor destroyed...just converted from one form to another.
The universe has not existed for infinity years because that would mean that it would be infinitely large, and, therefore, there would be a star at every point in the sky. A star at every point in the sky would mean the night sky wouldn't be dark.

matter can be created and destroyed from and into energy E=m*c^2 and m = E/c^2 also energy can be constructive = cos+sin 45=+2 225=-2 and destructive = cos+sin 135=+0 315=-0 interference so background radiation is infinite and as far as I can say it is eternal oscillating solar parsec and galaxy oscillations maybe even universal oscillations if interdimensional nature exists such as parallel worlds .... E=m*c^2 belongs to einstein and cos+sin can be seen in triginometry so I'd say it's eternal and the only consistency is background radiation

But matter can change into energy and energy can change into matter. The concept of infinity was created with the origin of the Universe.
