The Paradox of Hilbert's Hotel

A great deal of religious philosophers believe that actual infinite can't exist. This is the basis of William Lane Craig's version of the Kalam cosmological argument. If an infinite number of things really exists, it leads to all kinds of paradoxes - perhaps most famously the paradox of Hilbert's hotel. A way in which Hazali shows the impossibility of an actually infinite number of thing is by imagining what it would be like if such a collection could exist and then drawing out the absurd consequences from it.
