Nothing exists outside of time.
Are you arguing this scientifically?
That requires evidence, like observing outside of time and proving that there is nothing there.
There are singularities of time which are awfully hard to observe.
Here is one.
Time slows on objects that are moving faster.
At the speed of light time slows to a stop.
Now a photon of light moves at exactly the speed of light all of the time, it really must.
So when a photon is generated , it moves on until it runs into something that can adsorb it, if the path of the photon is unobstructed it could cross billions of light years , but the photon itself would not experience any passage of time, it may be a good thing that they do not carry watches.
So the Hubble Telescope has intercepted photons that have come to us from thirteen billion light years away. To us they must be thirteen billion years old because they have been traveling thirteen billion years across all of that space.
But if you could ask one of them, she would claim to be a newborn. Time has not passed for her.
