It is only an endless wheel because the religious believers that an infinity could be real refuse to even try to prove it.
They make the same unsupported claim over and over, an infinity is possible, yet have not once proven it is possible.
No infinity is possible. It is not an achievable amount.
Perhaps you could cite an example of a prominent theist refereing to eternity as something which has been "achieved"
Achievable implies a finish line. That would be a contradiction of infinity.
If God died He would not be eternal.
Let's cut to the chase.
Heaps of atheists and biblical theists agree upon the (metaphysical) plausibility of past-eternal things - God, multiverses, etc.
If you say nothing infinite is really real what else is left? A continuum of impermanence?
