Ty, you've made the assumption that maths applies and logic applies.
A couple of reasons why its not safe to assume. In the real world, all energy was created at the start of the universe and energy cannot be created or destroyed. This is what drives a lot of the physics, which is based on maths, in the real world. There is an energy to mass conversion which was the start of the universe and there is often mass back to energy conversion such as in nuclear fusion inside our sun which keeps us warm and sustains all life. This conversion is running now inside your body, energy from the sun converted into hydrocarbons in plants which eventually converted to energy in the mitochondria in your cells, and so you have energy to type your reply. Easily proved this is true - stop feeding a human food and they die.
In the aspect of "soul" and "heaven" well apparently souls are created from nothing, but not apparently never destroyed. So completely different rules? So run with that thought.
Suppose "soul" is a unit plucked from a fixed-size blob of "soul-energy", that implies at some point there isn't enough soul-energy and humans must eventually be created without a soul. As a soul has no clear manifestation we can point to, we'd never know when god stopped making people with souls. Perhaps that's already happening now?
Next, suppose heaven has a fixed-size, at some point for 1 person to go into heaven, the soul of a previously dead human has to be expunged from heaven. Now as we struggle to know much about all the people in generations long-gone apart from the famous ones, even if you did go to heaven, you'd never know that someone you never knew ever existed in the real world had their soul destroyed by your entry. After all, heaven could have been constructed without view of 7B current population.
I think the Christians currently believe that there is an infinite supply of soul energy, heaven is infinitely large, all humans have souls, etc.
Also the maths needs to scale. There is highly likely in the real world that life exists on other planets and that some of them have intelligence comparable to higher to ourselves. So what did god do there? Did it give them souls or not? If apparently on our planet lower life forms, say the great apes, didn't get high enough in god's pecking order to be given souls, is it that heaven only takes the 1 species from 1 planet, or is it all intelligent life on multiple planets? So in heaven we'd be mixing with aliens? Within our species do all, even those with severe mental problems have souls? Also, rolling forward as our species evolves, do we at some point drift off the acceptable parameters if deserving a soul? Evolution is really happening in our species, it can be proved, for example there is a sense of smell of certain chemicals that some of us can smell, others can't smell and this is traceable in the children, so genetics is already proved.
So you either have to hold to logic which creates maths, and apply logic rigorously or just ignore everything and make it all up.
So, even though there is no physical method by which a soul can exist, no physical method by which God has directly influenced the real world, no physical method by which a heaven exists, nor the method of the conduit between these realities, no prove that any of this real, you've *assumed* that in our real world the logic contained in maths (e.g. 1+1 = 2) is still actually itself maintained in this alternate reality called Heaven. Heaven could be, and probably has to be as it has no conduit into our reality, run on entirely different fundamental rules, with different maths and different logic altogether.
So I challenge that maths can be applied.
