We know nothing about the existence of a Creator of our Universe. We only have evidence for the existence of the Universe.

Another misinterpretation.
What I said doesn't refer to me personally. My use of ''we'' refers to the human race..... ''we'' as a species.
And yeah, I know that there are people who claim to have evidence for the existence of a Creator, the existence of deities, but where is the evidence they claim to have? What it says in the Bible? The Quran? The Gita? Is that the evidence?

Yeah, the Creator is what....7 or 8 thousand years old? That's way older than if you add up all the "begats" in the Bible.

That's absurd. Do you really think that there is "tons of evidence" that falsifies the fact that many people hold no belief in gods?

You need to invest in a dictionary. Or are you just trying to create a strawman to argue against?

Here's an article that may educate you a bit about what atheism is:

You shouldn't say it. Not for the reason you believe, but because it is wrong.

One example will do for a start. Thank you.

I'll collect a list of age measures, both primary terrestrial and celestial. All are in years.
Here are the earliest events in our Universe that have left details of them. For each of them is the time since the inflation era.
If one could observe primordial neutrinos, then one could observe to about 380,000 years earlier, to about 1 second after the end of cosmic inflation. Likewise, if one could observe primordial gravitational waves, either directly or as imprints on the CMB, one would go all the way to that event.
Primordial nucleosynthesis took protons and neutrons from earlier in the Universe's history and made deuterium (hydrogen-2), helium-3, helium-4, and lithium-7. Leftover protons became protium, hydrogen-1.
Cosmic inflation was a very early period of exponential expansion, and it had an expansion timescale of roughly 10^(-36) seconds. It took about 60 e-foldings to produce the volume of the observable Universe, and it likely continued for more than that.
Quantum-mechanical fluctuations got frozen into the Universe as they got stretched to more than the horizon size. These fluctuations produced primordial density fluctuations and primordial gravitational waves. The density fluctuations' existence is well-established, but the gravitational waves have yet to be convincingly observed. There was a false alarm about them a few years ago with the BICEP2 telescope's results. So those fluctuations are the oldest Universe details that we have been able to find evidence of.
