In atomic scale everything becomes invisible, I call it invisibility range that's the real deal here because some other mathematics and physics laws fails here.
Invisibility or visibility does not prove something exists. It does not prove God exists.
I will give you an example.
When you look in the sky at night, you see many stars. These stars are so far away. The closest one, Proxima Centauri, in the Alpha Centauri star system, is about 4.246 light years away.
Light from this star takes 4.246 years to get to earth.
That means, when you are looking at the closest star to us (apart from the sun), you are not seeing it as it is right now, you are seeing it as it was sometime ago, sometime in our earth year 2020, that is when the light we see today from Proxima Centauri started its journey from that star.
So, if Proxima Centauri were to undergo a sudden supernovae and extinguish itself today, we would not know that right away. We will start to know that sometime in the year 2028.
So, when we look at Proxima Centauri today and say "There is Proxima Centauri, we know it exists now, because we can see it", that is a product of our ignorance. We do not know that Proxima Centauri exists now. We can't know this. Because light from Proxima Centauri takes 4.246 years to reach us.
This is only the closest star. There are stars that are millions of light years away from us. Our closest large galaxy neighbor, the Andromeda Galaxy, is some 2.5 million light years away.
That means, when we look at light from the Andromeda Galaxy, we do not see the galaxy as it is now, but we see it as it was some 2.5 million years away.
Light from the sun takes about 8 minutes and twenty seconds to get to us. That means, if the sun suddenly goes dark right now, we will not know that for another 8 minutes and 20 seconds.
So why are you putting so much importance on what we can see, while a lot of what we see doesn't even exist ( example dead stars that died million of years ago, but we still see them because of the speed of light limit)?
Why are you making visibility or invisibility important, if it cannot even tell us if something is there or not?
