No...... read the second sentence. they are saying we science takes us back to the birth of our universe. Our universe did not just exist... it started 13 billion years ago.
If you wish to say that something had to come "before" you are pretty much admitting their could be a Creator.
Is that the second or third time I have had to explain that on this thread alone.

Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.[13] This singularity signals the breakdown of general relativity. How closely we can extrapolate towards the singularity is debatedâcertainly no closer than the end of the Planck epoch. This singularity is sometimes called "the Big Bang",[14] but the term can also refer to the early hot, dense phase itself,[15][notes 1] which can be considered the "birth" of our universe. Based on measurements of the expansion using Type Ia supernovae, measurements of temperature fluctuations in the cosmic microwave background, and measurements of the correlation function of galaxies, the universe has a calculated age of 13.772 ± 0.059 billion years.[17] The agreement of these three independent measurements strongly supports the ÎCDM model that describes in detail the contents of the universe. In 2013 new Planck data corrected this age to 13.798 ± 0.037 billion years.[2]
