Where did the universe come from? Atheistic origin science has no answer.

So one option is that the universe, which we can observe and thus know exists, has always existed in some form or other. The other option is that god, whom you claim cannot be observed and therefore cannot be proven to exist, has always existed and created the universe. Seems that the former explanation is simpler and more likely, and does not require us to presume the existence of things we cannot possibly detect.

an unassailable fact : universe is 13 billion years old.

"whom you claim cannot be observed". that part is correct. for instance, an entity standing right in front of you claiming to be God wouldn't be proof.

More uninformed, ridiculous babbling, throwing out half-formed assertions just to see what sticks.

The first direct observational evidence that the universe has a finite age came from the observations of astronomer Edwin Hubble published in 1929.[21] Earlier in the 20th century, Hubble and others resolved individual stars within certain nebulae, thus determining that they were galaxies, similar to, but external to, our Milky Way Galaxy. In addition, these galaxies were very large and very far away.

Spectra taken of these distant galaxies showed a red shift in their spectral lines presumably caused by the Doppler effect, thus indicating that these galaxies were moving away from the Earth. In addition, the farther away these galaxies seemed to be, the greater the redshift and thus the faster they seemed to be moving away. This was the first direct evidence that the universe is not static but expanding. The first estimate of the age of the universe came from the calculation of when all of the objects must have started speeding out from the same point. Hubble's initial value for the universe's age was very low, as the galaxies were assumed to be much closer than later observations found them to be.

The first reasonably accurate measurement of the rate of expansion of the universe, a numerical value now known as the Hubble constant, was made in 1958 by astronomer Allan Sandage.[22] His measured value for the Hubble constant came very close to the value range generally accepted today.
